Given that my Model 3 seems to think (visualized on the screen) that my garage door is a semi-trailer pointing towards me, I'm inclined to not believe that they can't do all of this with cameras only.

I'd love to see the convincing data RE: radar - they're using the same radars as every other car that has emergency braking from the car in front of the car that's in front of you. I've not heard of many "phantom braking" sessions from these other vehicles - I may have missed something.
Allow me to take you for a drive in my Volvo V90. I turned the auto-braking feature off entirely because it spits false positives like crazy. Parked cars, signs, birds, cars travelling through roundabouts across my nose, nothing at all - they all trigger it, and the car stomps the brakes extremely hard. The 2017 VW Golf it replaced was FAR better - maybe two false positives in 5 years. The Volvo? Daily.
Where do you drive? I feel at least some of it depends of driving style and culture... Rental MB I had in Spain had phantom braked few times a day until I eased off. Other cars in LT and NZ - maybe once a month or less.
And by phantom braking I mean emergency braking a bit too early - i.e. I am perfectly aware I am too close to a car in front, I have foot on brakes and I see how traffic flows, yet the car brakes.

> 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.
Lol that's horrendous. I had a Mercedes with automatic parking assist back in 2016 that would do it perfectly 10/10 times, used it all the time too(narrow streets in the UK). What's shown in the video is just hilariously bad.

> Cars without radar still aren't at parity with the car that have it Tesla Vision outperformed Tesla with Radar in the official tests.
I guess I'll do the obvious and ask for a source. I saw the Tesla Vision keynote from Karpathy, if that's what you mean. Wouldn't call that a source for "official" tests.
The Tesla Vision only was tested by some state agency and has a higher score then the radar one. But only in terms of safety, I guess the software does other aspect as well.
There should be Tesla blog post about it or something.

Euro NCAP tested it. It doesn't get more official than that around here.
Re: Tesla Vision Update: Replacing Ultrasonic Sensors with Tesla Vision
#216There are multiple tells that this move, just like the removal of radar, is supply-chain and cost-driven and not actually driven by engineering. If this were a planned move, the software would already be ready to replace it. It is not. Cars without radar still aren't at parity with the car that have it, although they "fixed" this a few weeks back by simply turning off the radar on the older cars. The parking sensors…

Automatic parking is part of a premium package, I don't have it. I do rely on the sensors often, particularly on the front ones.
This removal is mindboggling without adding a front camera.

Model 3 vision only does the same.
How often would you say you get false positives with your Model 3?
Re: Tesla Vision Update: Replacing Ultrasonic Sensors with Tesla Vision
#218This would potentially work... if the cameras could see the places where the ultrasonic sensors were. But they can't! There are big blind spots near the bumpers. I guess they are planning to just have the car fill in the blind spots by remembering what it saw from other perspectives? But that only works when the car is moving and can't account for small obstacles that can move unpredictably, like animals or toddlers.…
I assume these new Teslas will have a bumper camera. No way they’re planning to rely on memory.
In that case they would need to maintain software for both loadouts or install additional camera to the cars they shipped up until now.

Birds you're about to hit with your car? That sounds like a great feature.

#220Does a Tesla have a rear parking camera ???.
