The autopilot has never followed at a fixed distance. It has a distance range, and it follows fairly closely as long as the car ahead goes faster, even just a little faster, than the follower. This is sensible behavior, because otherwise, for example, the autopilot would have to brake whenever...

When I look at actual accidents, caused by human drivers, the cause is overwhelmingly a driver mistake in good visibility. Even in poor visibility, accidents do not rise sharply. You get a strong increase in the accident rate only when at least two problematic conditions come together, such as...

I believe the starter relay in ICE cars, also called solenoid, is very different, because it does not only switch on the starter current, but also, as Wikipedia explains: Thus the ICE starter system is more convoluted and more error-prone than the simple standard relays in Tesla cars. If, as...

To my knowledge, no. You worry too much. A relay switch causes incomparably less wear and tear than starting an internal combustion engine.

A little correction. If somebody drives hundreds of miles every day and always supercharges, it would age the battery significantly. Fortunately that is very far from normal use for almost all of us. The battery degradation we have to cope with is calendar ageing. Our batteries are quite...

Yes, that's possible. However, an overpessimistic mileage display does not hurt anybody. As long as people charge as many miles as they need, they will get as far and will never run out of charge before zero. Everything will work fine. The only exception is that the maximum possible mileage...

I suspect the first of the two links refers to NMC batteries, not LFP. LFP batteries have a near-constant voltage at a constant load or at no load over a wide range of states of charge. A more precise determination of the SoC from the voltage is only possible at very high and very low SoC...

VW, BMW also. There are oncoming European driving safety regulations that demand such functions in the near future, so all new cars will have to have them.

I've heard that before, but I have doubts. However, the topic is so complex that we'd need a lengthy discussion, and arguing might still not lead to a convincing conclusion. On top of this the question is not that important for practical purposes. Since Tesla recommends charging to 100% from...

So do we agree that the best current workaround for cooling is to split the air stream by spreading two fingers on the touch screen, and also lifting the air stream to the highest position? Not counting extra equipment, that is. For heating there is a simpler, near-perfect solution—switch off...

LFP batteries are tolerant of different charging styles. Even if frequently charged to 100%, they may still last for a million miles. So you can pretty much charge them however you like. If you want your car to last for a very long time, longer than, say, 10 years, and you want to treat the...

Possibly the nav display autozooms when it is set to keep the map in driving direction. It does not auto-zoom when set to north-up. I have not tested this thoroughly though. Another point is that with driving-up you can zoom manually, with two fingers, but the map will return to auto-zoom after...

I like to have at least 20 miles to spare. However, when I drive to a non-Tesla fast charger, I check for an alternative and try to have at least 10 miles left at the alternative, in case the first one fails. I also check the energy screen and drive more slowly if consumption is higher than...

Fact is that they are calibrated during normal driving. They are considered unreliable until they have seen enough driving. If this is so, then they can be, and most likely are, continuously or occasionally recalibrated during normal driving. This means there is no need to recalibrate them...

I thought we are talking about driving in London. The Autopilot does not work well with tight bends, unless you set it to a low speed.

You get a collision warning when you are on a trajectory that would cause a collision within a short time when continuing. Depending on your driving style this can happen often in dense traffic. It is a signal that you could ponder improving your style. Avoid accelerating towards other cars...

That's not possible, unless the number of parameters is very low.

It would be easy to take a video clip of this behavior. Take a video such that one can see the D top left on screen and the car beginning to move.

I recalibrate never. No downsides so far either.

I would be surprised if we had to do that. The manual would have to mention it. I believe (but do not know for sure) that the cameras continuously and slowly recalibrate themselves.

Check teslalogger.de for expected range for your particular model.

That is correct. Other factors could play a role. I do see, however, that in the described cases there is indeed an obstacle. Why TACC does not brake every time, we don't seem to know yet. In any case it seems that the new autopilot (FSD Beta) recognizes such scenes correctly, so discussing...

You are writing about the old autopilot/TACC, not the FSD Beta version. This makes it not very interesting, as the old autopilot is going to be replaced. Tesla isn't exactly working on it with any intensity. My guess is that the autopilot sees the obstacle straight ahead. It is not clever...

A rough, but still fairly good way to determine your battery's capacity is this. Charge to 100% and leave the car connected to the charger for another half hour or more. Switch the display to miles or km and read the range. Open Degradation , select your exact model, and click the OK button. In...

Assuming you don't have the climate controls on Auto, you can wipe down from the little < and > symbols left and right of the temperature. This opens the small climate menu that includes seat heating.

One thought is that you can get at everything in the frunk at any time, as opposed to the trunk when it is loaded. With a full trunk you cannot even get at the lower compartment without first unloading half of the upper trunk. This is my reasoning for putting everything in the frunk that I need...

Yet another problem of FSD is that most people like me, who change cars very often (in my case because used Teslas are sold for more than the price of new in Germany), cannot afford FSD. I've had it in my first Model 3, but used car buyers do not appreciate it for the most part. If I bought FSD...

As to poor efficiency, there is one more possible cause. Some people have a habit of continuously varying the accelerator position. Some do it because they hunt after the desired speed, for some it is just a peculiar nervous habit, and everybody varies the pedal position at least a little bit...

It's different in different places. In Germany a used Model 3 RWD, without any price-raising options, that is a half year or one year old sells for more than the effective price of new, so it's actually a very good investment. The reason is that Germany refunds €6,000, the manufacturer (Tesla)...

Check this.

Bad choice. If you choose a place where the supermarket is much higher and you buy heavy loads of stuff, you can produce electricity and never need to charge. :cool:

That certainly won't cut it, because many here, or perhaps many Tesla drivers anywhere, are already "100 percent or 200 percent or more safer than the average human driver" when they drive manually. The average human driver drives dangerously. I guess 10 times safer will cut it.

I forgot to mention that speed limit recognition is not yet enabled on multi-lane freeways (like the autobahn in Germany).

That's what TACC does. As has already been said, holding down the gear stalk half-way for two seconds changes speed to the currently recognized speed limit. The Autopilot, however, works differently. It will lower your speed when recognizing a new speed limit. It will even raise the speed...

Thanks a lot for these graphs! I think they answer my question nicely, at least for the first 9.1 months. An interesting detail for LFP batteries is that there is a plateau between SoC 40% and 70%, i.e. I'm not gaining anything by lowering the SoC from 70% to 40%. I would have to put the SoC...

My lower trunk compartment is almost always empty for the simple reason that I cannot get to it when the trunk is full. And when the trunk is not full, I obviously don't need it. The only situation where I use it is when I travel and need the entire space including the secret chamber to pack...

Of course I have read the manual. If my last name were Tesla, I would write the same, because I would want to make sure that the battery does not go down to 70% within 8 years or 160,000 km = 100,000 miles, i.e. within the warranty limits. But as I had written, I'm asking for 20 years and...

Thanks. Where exactly do you know this from? Do you have a link or two?

I have a very specific question about the LFP battery in the newer Made-in-China Model 3 RWD, to which I could not find any answer so far. Assuming I want to drive my car for 20 years and 300,000 miles with its original LFP battery and assuming that the car is being slow-charged whenever it is...

I, for one, do not like noise. It also serves no purpose. When somebody walks in front of my car, I don't know whether the person is blind or deaf or normal. So I do not run them over anyway. Knowing that I have no sound makes me careful. The purpose of the AVAS regulation is to defame...

To the best of my knowledge, in March 2020 the Model 3 had no AVAS/PWS. There was no speaker.

They have done a good job at keeping the heat pump noise within limits. I occasionally hear it, but even then the sound is relatively pleasant, not disturbing, and the sound level is low. I, for one, have no reason to complain.

Meanwhile I have. My idea works exactly as described. First turn the steering wheel to the left stop to get the wheel out of the way. A little detail from somebody who is not a car mechanic: The three little plugs that hold the wheel well liner to the front bumper are very easy to operate once...

The answer is yes, but I would say, use both for best comfort. I have everything set to "Auto", and it nicely controls both seat heaters and climate. The only thing I control is the intended temperature. In my experience this works very well. Seat heaters are automatically activated when...

Down with the looms.

Stand near the front of the car and have someone engage the forward drive gear ("D"). You should hear the sound. Perhaps stand beside the car, not directly in front of it, just in case … :) The sound resembles white noise, a hissing sound. You can also test the reverse sound by asking the...

I have a little bit of a doubt, but have no really good information. From independent studies on LFP batteries we know that regularly cycling the battery up to 100% with moderate currents, like AC charging, does not cause any significant degradation. In cooler temperatures, like 15°C = 59°F, the...

A long time has passed, but two points have still not been discussed here. Making the modification deniable, i.e. it should look as if the contact was not properly installed when the car was manufactured or as if it broke or worked itself loose during normal use. Making the modification such...

Yes, exactly. If you want to extend the lifetime of the battery to the ultimate max, try to keep it between 40% and 60%, i.e. charge it whenever you can to 60%. Keeping it between 20% and 80% will reduce its lifetime a little bit, compared to 60%. Fast-charging and charging to 100% also...
