Sounds like worn cv joints. Fairly common. You can try turning the steering wheel all the way to the right and driving around for a few full circles. Do the same to the left. This sometimes redistributes the grease in the cv joints.

Sapphire's top speed is 205 mph, similar to Plaid's track package. The Plaid has higher gearing than the previous performance Model Ss, so even at 200 mph the top motor rpm is about the same as before. The carbon fiber will be needed for the Roadster with its 250+ mph top speed. Although, the...

The Plaid against the Sapphire was on 21s and posted a 9.288 at 150 even while not in full cheetah mode.

Yes, each drive unit has its own oil pump. They can sample the DU fluid by the drain plug to check for coolant contamination.

Maybe they can detect the load on the electric oil pump in the DU? If coolant entered the DU, it could change the viscosity of the oil. There is a vent at the top of the DU where hot coolant vapors could escape / condense.

I still have the vibration. I would say it is less but still quite noticeable. Can definitely feel it through accelerator pedal.

Because of poor weather conditions, he expected to run mid 9.20s. He ran a 9.26. He ran a 9.19 two months ago at 90% charge.

Using the published horsepower vs speed plot and taking into account the rotational inertia, loss in the gear box, rolling resistance, tire slip, aerodynamic drag and the mass of the car plus driver, the 170 lbs of removed weight makes a 0.113 second difference in elapsed time in the quarter...

My point is the curve is not as flat as Tesla says. This car has 47 hp more at the peak but 86 hp less at 200 mph than the perfect horsepower plot.This car's hp decreases by 177 from 80 mph to 200 mph, whereas Teslas plot shows a loss of only 62 hp. Also, this could be a car that has more hp...

Absolutely, it's better than a P85D. That had induction motors that are subject to back emf and limited battery voltage. The Plaid has an excellent hp vs speed curve. I'm just saying it doesn't look like it's as good as Tesla says it is. Sort of like the hp they claimed for your P85D.

It's printed right on the bottom of this image. They don't mention multiple pulls. The image you posted is "real time" as they did the pull. Then they immediately fade into the uncorrected plots.

That's corrected data. It's being corrected for the local density altitude which doesn't affect electric motors. That's why they show the uncorrected data later in the video. I mean "already" because the hp curve isn't as flat as Tesla says it is. At 160 mph it should be 1004 hp, but on the...

Plaid has 1067 peak hp (uncorrected) at the hubs and is already down to 948 hp at 161 mph. So at 200 mph it looks like it would be down to 890 hp where Tesla's plot puts it at 976 hp. That's falling off a lot faster than the perfect horsepower plot that Tesla made available which may be why...

On the P85 since there was no issue with traction, you can see that the beginning of the hp vs speed is dead straight, implying constant torque. The P100D's torque increases from its initial value. You can see this because the slope of the hp vs speed curve gets steeper with speed. The Raven's...

Horsepower is the product of torque and rpm. That is, torque is Horsepower divided by rpm, so both horsepower and rpm affect torque. Below a certain rpm for a given horsepower the torque becomes greater than the traction the tires can provide. At this point the pre-programmed torque is just...

Tesla has a pre-programmed torque curve for launch that's designed for 19" summer tires on asphalt. Or at least it was on the Raven. This torque curve keeps the tires on the edge of their traction limit, until the torque is limited by horsepower and speed. For small amounts of tire slip, the...

30 lbs is 0.02 sec. I'm not sure what meaningful means. If you win by 0.001 seconds, you win.

I know 0.02 seconds doesn't seem like a lot, but it's 4.4 feet at 150 mph. Even if there are other random events that affect the performance, on average you'll get to the 1/4 mile 4.4 feet ahead. Races are won in the thousandths of a second, after all.

Not to mention the greater rotational inertia off spinning up the transmission and engine. In first gear this rotational inertia can increase the effective mass of the car by 35 percent.

In Denver when the temperature is 90 degrees F the density altitude could be around 9000 Ft. At that altitude the air density is 76% that at sea level. If I integrate the net force from the motor minus rolling resistance and aerodynamic drag for that difference in density over 1/4 mile, I get...

1025 miles on my model s plaid, and it just started to vibrate. Also noticed some mild lugging like an ice in too high of a gear. Happens with mild acceleration around 40 mph. I had the issue with my half shafts on my previous model s, but the vibration was different. It was at a lower frequency...

This was years ago, and the manual had new language about obtaining speed limits using the camera. In order to confirm this, I wanted to prevent the car from using its gps database to obtain the speed limits.

Don't you have to place an order on a car to request a trade-in quote? I guess you could order a Model 3 and a Models S to see if they quoted different trade-in values. It'd cost $500 to find out though. Even then I think you have to wait until a vin is assigned, so unless both vins were...

Forget about my particular situation. No-one is actually getting a $3000 discount. Since they require you to trade your car in, they just lower what they offer you for your trade-in by $3000. This is why at a normal dealership you shouldn't tell them you have a trade until you negotiate the...

You seem to be missing my point. I'm saying it isn't a loyalty program at all. It's a sales spiel. If it was about owner loyalty, you should get the discount if you currently own a Tesla, even if you don't trade it in. They require the trade in so they can recover the discount through the trade...

This was my question: "If it's a true loyalty program, why wouldn't every current owner who's buying a new car now get the discount?" They don't. They have to trade in their current vehicle. Why would that be?

I got a loyalty discount on my current Model S which is leased. I got the ludicrous option for free. I guess loyal lease holders aren't really loyal anymore? Or it's not really loyalty, It's a typical car sales scam.

I'm returning my current Model S lease vehicle and leasing a new one. I called and asked if I was entitled to the $3000 "Ownership Loyalty Offer". I was told it's only for trade-ins. It's the old trade-in shell game. They tell you they'll discount your purchase only to subtract it from what they...

if you look here, Tesla explicitly prohibits sales to third parties: https://www.tesla.com/support/leasing/lease-end-options " Purchase Your Tesla You may be eligible to purchase your leased Tesla. Review your lease agreement to see if you qualify. Eligibility Model 3 and Model Y are not...

I have a Nov. 2021 Model Y LR, and I can see the wiper arm from the drivers seat. The car has been sitting for 24 hrs in the garage. They were set to automatic, so I turned them off and waited 5 minutes. I could still see it. Also tried carwash mode and still visible. Part of the passenger...

I agree that using neural nets to generate the heuristic is POC.

I took all that to mean that the Euclidean heuristic is being replaced with a better heuristic that is generated by the NN and used in the tree search. That doesn't preclude the coarse search algorithm from using a mcts with the Euclidean distance or some similar weight function.

There is an adapter available that converts the Tesla proprietary wall connector to the standard J1772 connector. With this you can use the Tesla wall connector to charge other evs. This is not the adapter that Tesla sells to convert level 2 chargers to the Tesla connector on the car.

They might be using Monte Carlo tree search for the coarse search part. It's supposedly the state of the art for heuristic path planning searches. The coarse search avoids local minima but can be too slow on a fine grid. Once the coarse search finds a convex domain, the continuous optimization...

Heretic! Of course it will be with cameras only.

Elon says they are at the end for their current method of generating a vector space from the camera images. According to him, FSD Beta V11 will have a whole new neural net that generates the vector space directly. All these 10.x release just seem to be stalling until they can get V11 out.

Same S**t Different Day

My screen on legacy Model S v11 (2021.44.25.6).

10.8--SSDD. These guys are flailing. As Elon just put it, the procedural vector space code has hit a local maximum.

On limited access highways it will be the same NOA whether you disable FSD Beta or not. You could temporarily opt out of Beta to return to the production version of NOA. It can take some time to get the new download after opting out, though.

It will be vision only NOA even if you have radar on your car.

It's not. It's coming in V11 which Elon says is another major rewrite of the neural nets. Apparently the building of the vector space is currently done in procedural code from a "bag of points with probabilities" the neural net generates. He says V11 will build the vector space directly using...

Was it still dark out. I thought this only worked at night.

I sold my 2013 P85+ to Carvana. They beat Tesla's offer by $10,000 and Carmax's by about $3000. It was pretty painless. They sent someone out to inspect the car, and he had the check with him. It was a pretty cursory inspection. As long as your car is as you describe it, there should be no...

Carbuyerusa.com offered me $65,300 for my Model Y Long Range with no options and 300 miles. It's a 2022 (November), but their drop down list only went up to 2021. So it would probably go for a little more if I contacted them and updated the year to 2022. The wife wanted to get rid of the car...

Good to know. I'm still waiting for my holiday update on FSD Beta for my legacy Model S. Currently on 2021.36.8.10.

A recent post said It had gotten much faster.

Legacy Model S/X don't get vision based autopark either, even though green was able to enable it on a rooted Model S.

My Model Y long range from November doesn't have matrix headlights.

No. But they did just pick one. He said they don't know which one is correct if they disagree, so what do they do now when vision is wrong? They have no way to detect this. At least if they had radar they would know they disagreed and that something was wrong rather than just blindly proceeding...
