I can confirm first hand, owning a legacy 2018 Model S with front facing radar and a Vision 2021 Model Y.

Aha so we’re talking about a Tesla design spec constraint not some fundamental safety thing or computational limit or some other physical barrier or whatever. Interesting.

Just from a physics stand-point, you can't bring your car to a safe stop (or any kind really) in two car-lengths at 85mph. If you take the most generous scenario possible, that the car in-front of you will continue for another two car-lengths (but at a slower speed than you), it's still pretty much impossible to bring your car to a complete stop in four car-lengths.

> The parking sensors on the Tesla are really good and very useful. I respectfully disagree. I think their primary use case is parking. Tesla does a really good job with automatic parking, and it IS useful especially for parallel parking. But honestly, I have curbed my rims and hung up my underbody front spoiler on a curb and they did not help. Really there is an opportunity for cameras to protect the car from nearby…

Tesla is probably the WORST at automatic parking. Here’s a comparison against some other competitors. https://youtu.be/nsb2XBAIWyA My own model Y has maybe successfully automatically parked 2/10 times. Most of my friends and coworkers have similarly low success rates.

This is pure comedy, thanks for posting.

“In the near future, once these features achieve performance parity to today’s vehicles” Right... like how vision vehicles have parity with autopilot speeds and following distance? Oh wait they don't. Vision-only vehicles are still limited to a max of 85mph and 2 car minimum following distance for autosteer while radar is 90mph and 1 car following distance. Texas has 85mph highways. The two car following distance con…

What's the point of using car lengths as a metric of follow distance.

Because humans are not good at eye-balling distance, especially while moving. The only other point of reference is going to be the only other thing travelling on the roads at a similar speed... cars. Hence, the rough comparison of "car-lengths".

Pardon me for being out of touch, but cars park themselves now? That's pretty neat

Another thing I missed the memo for, 360 degree birds eye view cameras. Game changer for parking.

Of course also missing from the Tesla due to the lack of a front bumper camera that would allow for it...

Tesla's own reporting out of China from Friday is that they weren't able to sell all the cars they made...

“In Q3, we began transitioning to a more even regional mix of vehicle builds each week, which led to an increase in cars in transit at the end of the quarter. These cars have been ordered and will be delivered to customers upon arrival at their destination” - [0] In other words, they said all of the cars had been ordered, although many were in transition at the end of the quarter. What is your source of what Tesla sa…

I mean isn’t that the same thing for traditional dealerships? They order the cars and they’re waiting to be sold. A good amount of Teslas end up rejected for whatever reason and show up on the existing inventory page. You can often find new cars in socal with delivery that week. I got my model s that way.

As a person who’s owned some luxury cars in their life, going from a BMW to a Model3 feels like a really big downgrade in so many ways. I can give a list of reasons why I didn’t buy an M3P at the time but quality, lack of repair options and really shitty interior topped the list. Not having carplay/android auto or satellite radio were minor but still annoying in a car that cost so much money.

We've had the complete opposite experience with our BMW->Tesla move. Sure, the BMW had a very nice interior, that complaint gets a tons of play online, and it's not inaccurate. But you know what just blows that away? Getting into a car on a 100 degree day, and instead of scorching my skin on the leather, like I would with our old BMW, the seat is cold because I tapped a button on my phone 5 minutes before when we wer…

Interestingly, all those features you mention are also available on BMWs from the last years. Your comparison is not fair if you compare against an old BMW.

On the other hand, on all the Teslas I’ve tried I missed basic things like proper traffic sign recognition, proper adaptive headlights, proper automatic windshield wiper activation, safe lane keeping assistant, etc. those were unusable and unreliable on all Model 3 and Model Y I’ve tried. Not to mention how helpful is the 3D view for parking, also not available in any Tesla.

Was the Tesla being driven in the FSD mode? or was this a simple human error?

My entire point is that even outside of FSD this is a scenario a base model Corolla has the technology to handle: AEB You don't actively engage AEB, at the kinds of low speeds involved AEB would have engaged and at least helped stop the car. This was traffic that was going maybe 20 mph, and the car still hit me solidly enough for my car to lurch forward and almost hit the one in front of me - But as an aside, this is…

Teslas AEB works but if the driver has their foot on the accelerator it won’t. And with one pedal driving, there’s the issue.

But it could also be a case of the person turned it off because of course Tesla let’s you control that.

IMO if the car thinks you’re going to crash it shouldn’t let you override AEB period. Why this isn’t a law…

Tesla reached a mere 1.5% share of new cars in August 2022 in Germany. They are far away from "outselling" all the others.

Germany car marked is skewed towards Germany carmakers. Apart from obvious reasons, car leases through employers are only for German cars.

I've yet to be in a country were sales are not skewed toward local cars. Sweden lots more Volvos than anything else (and definitely Teslas), France, lots more Citroen and Peugeot than anywhere else, Australia: Holden and Ford, US: lots of cars that drive nowhere else (GM, Chevy...).

Regarding outselling most other car manufacturers: this seems to be the Tesla realitity distortion, it is likely true for electric cars but for all cars VW delivered ~5 M cars in 2021 vs Teslas 900k

It's most likely a hardware availablity issue. They have run out of sensors, and they don't want to pause production until they have produced more.

Seems like the "upstanding" thing to do would be to ship without (and credit for the omission) and offer free retrofit once available.

That would be an extreme logistical and costly nightmare.

Tesla doesn't operate the dealership model, which all tend to double up as a service station. So it's far more difficult for customers to get to the telsa service stations. Since there's less, that also means they'd be insane waits when the product comes back in.
