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.

Model 3 vision only does the same.

How often would you say you get false positives with your Model 3?

[tyfon]

I have a model X raven (2019) and model 3 awd (late 2021), both have radar and hw3, and both have the update that has disabled the radar.

Pre-patch there was maybe a phantom brake (hard brake) every six months, but lots of small slowdowns where you could almost sense the car got conflicting input (once pr 100 km maybe).

The latter is gone and I have not had any phantom brakes yet, but I've had a slow down where a bus went into my lane. The cars behaviour in stop and go traffic is also much better now.

The only regression I've found is that it's a bit more confused in a local spot where the road splits in two in a turn to the right. In the past it went into the right lane without much fuzz, but now it is confused for a second or two before it decides on the right lane.

Tbh, as a daily user of these cars I think the no radar update was an improvement.

Since the issue is reproducible, you should find a bug on it. Tesla is responsive and this will help everybody.

Every single time I use autopilot. I stopped using it.

Also, my experience with the Volvo one (on XC90 tho) was that it would happily plough into cars standing at a red light in front of me if I would let it.

TM3 has never had this issue for me.

> birds

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

[Daneel_]

Birds flying across the nose of the car half a dozen or more metres away. Not a chance of hitting them.

[grandpoobah]

But we already have a deal with the birds...

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.

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

[danuker]

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.
