As a Tesla customer I’m so used to being constantly gaslighted that it’s a pleasant surprise when they’re only removing features from new cars rather than my existing one.
Just wait until they stop supporting our legacy ultrasonics in software.

#232Re: Tesla Vision Update: Replacing Ultrasonic Sensors with Tesla Vision
#233There 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…
With the removal of radar, they showed some pretty convincing data that the radar was too noisy to be useful, especially with discriminating things like highway overpasses vs. stopped cars. They showed that vision could already outperform radar. With these parking sensors it's different. They have no current alternative and it will cause a pretty significant loss of functionality. Disappointing move.
> They showed that vision could already outperform radar.
important to note that much like there is a wide range from bad cameras (“filmed with a potato”) to high resolution cameras, there is a wide variety of radars with different capabilities.
the radar unit in Teslas was pretty limited (basically designed for adaptive cruise control), and they showed that vision could outperform that radar (and have no interest in exploring non-vision approaches because “humans can drive with just eyes”)

#234Does a Tesla have a rear parking camera ???.
Yes, these are the camera angles.

The main issue is that none of them sees right ahead the front bumper and they of course don't work when obstructed.

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.
How much time would you have to brake, if the car ahead came to a sudden stop (for example, due to a crash)?
If less than one second, you are almost surely tailgating.

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.
I drive a 2018 Hyundai IONIQ EV. The forward radar is hit-and-miss in heavy rain: the car will often barrel quite happily into stopped traffic when it’s raining hard, requiring a stomp on the brake pedal.
Just a couple weeks ago I was driving on the motorway around 4am, no other traffic for miles, and the forward collision alert sounded and the car slammed on the brakes for ~quarter of a second and then released as if nothing had happened and we merrily resumed our journey. Having the brakes slam on at a smidge over 100 km/h gave me a sore shoulder and quite the rush of adrenaline, quite the rush at 4am!
So yes. The radar does have a mind of its own.

> birds Birds you're about to hit with your car? That sounds like a great feature.
Birds flying across the nose of the car half a dozen or more metres away. Not a chance of hitting them.

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.
In some weird way having multiple cameras + touchscreen, smaller mirrors and beeping parking sensors made it all much more distracting.
I used to parallel park in seconds, now it's an ordeal.
Life is difficult without backup camera tho.

In Sydney, Australia. I’d say I’m quite a conservative, safe driver (I have kids). I don’t tailgate, and actually I’ve never had it false positive on a car driving in front of me. It’s typically on stationary objects, or small moving objects. Or on nothing at all shrug

Now imagine that in the snow, when going around a corner on a cliff.
Welcome to Canada 11 months of the year, with wolves waiting at the bottom of the ravine, as you crawl, injured, out of your car.
And no, wolves will not be appeased with either maple syrup or poutine, trust me I know, I've tried.
