The new software update is a big step back in identifying speed limit signs in Colorado. The car constantly thinks the limit is 45 in a 65 zone. It makes AP nearly useless. Very frustrating. This used to work. Even Google maps has the limit right.

What does a L2 house charger actually do for the ~$500 price, besides provide an appropriate plug? It doesn't change the voltage. The current is controlled by the car and protected by the house circuit breaker. Why can't we just directly plug the car into a NEMA14-50 outlet?

With the new update, 2022.20.6 and .7, the car misses a lot of obvious speed limit signs. This is on rural 2 lane highways in Colorado. As a result, autopilot will often restrict me to going 50-60 in 65 zone. This makes autopilot useless....! I note that Google Maps is giving me the correct...

I had to refill the rental bobcat. Damn, diesel is expensive. BTW, the bobcat + trailer weighs 7000 lbs. The car did fine--thankfully I wasn't going far or fast.

I don't need a pickup truck..... I know the car is only rated for 2000 lbs, but it was stable. It helped that I also had 800 lbs in the car. It is amazing how much power the car has. My range was reduced by 40%. And I'm glad the supercharger was mostly empty.....

The speed limit sign recognition is not working at numerous locations on US Hwy 285 in Colorado (a major 2 lane highway). The signs are quite obvious and clear. It seems to be missing several 65 speed signs where internal navigation data with wrong speed limit data is overriding the clear...

I need to leave the car for 6 days in the cold Colorado mountains with no cell service. How do I avoid unnecessary drain? Turn off climate conditioning, sentry mode, scheduled departure..... anything else? I wish there is a button for total hibernation, rather than doing all the little...

We are seeing some 3rd party (non-Tesla) superchargers. But, I don't see any that offer a Tesla adapter. This seems strange since they would get much more business with a Tesla adapter. The CHAdeMO Adapter has been out a while. Why don't they offer a Tesla adapter??

I used the Glenwood Springs & Grand Junction SuperChargers. They are surprisingly busy, only 6 V2 stalls, 120 KW max. And there not others close by. This doesn't really seem like enough for I-70 in Western Colorado. Are there plans to add more???

I went into the remote backcountry and parked my MY at the trailhead for 3 days. It had 146 miles on the battery. It was 15 degrees Fahrenheit. No cell service for miles. I put my phone in airplane mode. The MY locked, of course. I needed to get one more thing out of the car so I used...

Along I-70 in Kansas, the superchargers are often very, very empty. It's unusual to see a 2nd car. If I go to a restaurant and come out 20 minutes late, will Tesla still charge me idle fees?

Our model Y has an "Off-road" mode that is very useful for snow. I assume this sends more power to the front axle and allows for a little slip. The model 3 could really benefit from this in Snow. I would think this is just a software update. I'm disappointed that this has not made it to the...

Interesting article of plugging an inverter to the 12V battery to power your furnace and refrigerator. I like it. This guy used a 2000 Watt inverter. Any idea how high of wattage you can go from the 12V battery? Tesla voids your warranty if you try to power your home with your electric...

While autopilot is generally impressive on curvy 2 lane highways in Colorado, I am a bit surprised it doesn't hold the lane better. It often drifts to the center line, near on-coming traffic. This happens especially on right hand curves. I think computers should be better at this......

Please post pictures of your Model Y. Here's mine in snow. The model Y did really well in the Colorado snow.

My Model 3 is a bit frustrating in the snow. Even though I have AWD, it sends too much power to the rear axle and the rear slides out. The traction control kicks in eventually, but not soon enough. However, my Model Y has "Off-Road Assist" driving mode which is much better in the snow...

When we gave a car to our son 7 years ago, I "embellished" it so that he would not feel too entitled about getting a car. For his Ph.D. graduation, we are giving him a model 3. How should I embellish this one, and have fun with it.....??

Wind drag is the major item using power when driving on a highway. I assume this drag is dramatically higher when pulling a trailer. Is it a 1.5x range reduction? 3x? Does anyone have and experience here?

A friend is buying a Model Y and asked whether it will be able to use non-Tesla superchargers. I gave this response below. Anyone have additional info? Yes, the car trip planner will show non-Tesla superchargers. But, it is not so simple. 1) There are very, very few non-Tesla...

That glass roof is too fragile. I have 41,000 miles on my M3 and just broke it a 2nd time. It's about $1000 a pop. So much for the car having low maintenance costs.......

My Tesla hit 42K miles and I got new tires. All places I call say that they can't do alignment on a Model 3. They say that in their regular meetings, they decided not to. But, much info says an independent shop should easily do the alignment. Strange. Has anyone found a shop besides the SC...

I got new tires and asked for an alignment. The tire shop said they can't do the alignment because they need the OEM scanner specific to the Tesla, which they don't have. They said to do the alignment at the Tesla SC. Anyone know anything about this? My model 3 is from Sept, 2018, VIN 059xxx.

5 years ago, I got a $50 parking ticket "add-on" for not having a front licence plate. My Model Y came with the front license plate holder not installed. I think it will take me 30 minutes to install (reading directions, finding the right tools, cleaning so the glue will hold) and hopefully I...

Having a nice EV causes my ICE car battery to fail. My wife and I are always driving the Tesla so my ICE car isn't driven and then the ICE battery dies. It's kind of ironic. I had this happen twice! After the first time, I bought a battery maintainer, but it was cheap and didn't work...

The speed limit sign reading is totally not working on rural roads (in Colorado). It's missing half the signs and it's consistently reading 65 as 45. This makes auto-pilot useless! And it can't be turned off--I've tried everything. I'm amazed more people aren't having this problem. I guess...

I took a 120 mile drive in Colorado on a 2 lane highway yesterday and the new auto speed limit sign detector failed quite a bit. It kept reading the speed as 45 when the sign said 65 !?! It made autopilot useless. Is it possible to disable the sign detector and go to how things were before...

Winter is coming. I want to get basic wheels for my snow tires on my Model Y. I've followed the other posts, but it's hard to find not too expensive wheels. I'm thinking 18" wheels, hopefully something aerodynamic, with sufficient load capacity for the Model Y weight. I'm looking at these...

I drive a 2 lane highway regularly where the one lane often splits into overtake zones and then merges. The autopilot generally starts in the middle and then suddenly swerves into the left lane. Using the blinker doesn't help. Then the merge isn't handled well. I always have to take it off...

When you are showing your Tesla to new people and taking them for a test drive, what do you tell them? The main points I make are: 1) The drive train is revolutionary: efficient and powerful. The battery only holds the equivalent of 2.5 gallons, yet gets 310 miles and better acceleration...

My FSD HW3 Model3 does pretty well on Autopilot, but it still has annoying problems with lane splitting and merging. When a lane splits, it generally goes in the left, fast lane. And when merging it also doesn't do a good job. Anyone has insight here?

Have you seen this interesting article how a reverse rocket box improves fuel efficiency? Tesla Model 3 with roof-rack box gets much better range if you flip box around - Electrek It makes sense. My current rocket box does not have the same shape and isn't so narrow at one end. Does anyone...

I went on a road trip in Colorado and charged at 2 SuperChargers (Silverthorne & Glenwood Springs). At both I arrived with the battery at 20% but I only got a max charging rate of 105 kW, and the rate dropped off significantly after my battery hit 50%. In both cases, the battery had ~60...

Tesla is offering free mud flaps in winter environments (Canada, Norway), but not in Colorado. We currently have very slushy roads. Do they help much? Should I get 3rd party mud flaps?

The Tesla CHAdeMO adaptor is expensive, $450: CHAdeMO Adapter Why so expensive? Is this a tricky thing to build? Are there any cheaper 3rd party adapters available? I searched but didn't find anything.

Can someone answer these questions: 1) If the car and battery are at 20F (-7C), how many KWh are used to bring the car and battery up to 70F (21C) ? I assume this doesn't make a difference whether driving or pre-heating. 2) How long does it take for the battery to heat up from 20F to 70F when...

A main reason range is significantly reduced in cold weather is heating the passenger compartment and the battery. It would be nice if Tesla would show energy usage of this heating and how much it is effecting range. This can help people appreciate the issue and perhaps get them to reduce...

Yes, EV's have reduced performance and range in cold weather. But, is the reduce range mainly from heating the battery and car? Can you keep the range reduction to a minimum by not heating the interior? The battery should still have the energy in it, even if cold. Yes, some energy won't be...

I'm going hut skiing in the Colorado mountains. I want to take the Tesla and leave it overnight for a few days where it may get down to -20F overnight. Then, I'll want to drive it when it may be 0 F (-18C). I'm not worried about reduced power or reduced regenerative braking. My main...

If you run out of battery, it would be nice it AAA or other services had an emergency charger to give you the extra 30-50 miles to get you to a real charging station. I think 10-20KWh would often be enough. And DC charging from battery to battery should be very fast and pretty simple. It...

It seems there aren't many new supercharger locations in the US in the last 12 months. Building hasn't picked up with the release of the new V3 version. We can use some more superchargers in Colorado.

I thought some of you flatlanders would appreciate this screen shot:

Good use of the roof rack.

I've noticed that range & battery usage estimates in the mountains are way, way off. It's not surprising since going uphill uses a of power while going downhill uses hardly nothing. I'm a bit surprised the Tesla range and battery usage estimates don't take this into account since it should be...

Driving home in 15F temps, the car electronics shut down at about 15%/50 miles on the battery. Still had the snowflake next to the battery display. The car was driving normal, but the screen was constantly rebooting and the garage door opener button didn't work. I wonder if the battery...

I'm noticing irregular battery measurements in the cold for my M3-LR. e.g. Expected mileage drops very fast (>2x than predicted) compared to normal usage (car is in 50 degree garage, driving in 30-40 degree weather, short trips) Battery drops 15 miles while the car has been sitting unplugged...

I was at the Denver stock show, which has many rural ranchers in attendance. A booth was advertising an insulated box for warming up newborn calves. I asked where it gets energy for heat. Answer: "that the beauty of it, it gets heat from the exhaust of your pickup truck. You always have easily...

At highway speeds, most of the energy is used for overcoming air resistance. Does anyone have experience in how much the range changes when drafting another car, or in heavy traffic where everyone is drafting? You could easily do this by just enabling adaptive cruise control with a following...

My AWD M3 does pretty well in Colorado snow, but does some sliding when accelerating with the rear tires breaking free. I think this is mostly a feature of the M3 weight balance and traction control being different from FWD cars with the usual heavy engines in front. I think it is safer for...
