My car randomly braked today because it thought a car on a side road was pulling out. Not just sound the alarm but actually apply the brakes. Fortunately I didn't have a tailgater behind me.
I disable the "land assist" every time (which often tries to steer me into wildlife or other cars and was clearly not built for use on a single track country roads with hedges and random verges), but this was the first time in 3 years that the "front assist" caused problems.
If that's "high quality", I dread to think what low quality would be.

- lmm 1y agoBraking at any point is safe with a competent driver behind. There's a reason we know our stopping distances and don't follow excessively closely.
- ta1243 1y agoAlas half of drivers are worse than average. I'm one of them. Yet I still haven't had a situation where "lane assist" or "front assist" has actually been a good thing.
- raxxorraxor 1y agoThat is unrealistic. If you expect the brake perhaps but the most competent thing to do in case of an emergency brake is doing nothing.

- izzydata 1y agoThis happened to be on a highway when driving my friends car with all these assisted driving "features" while in cruise control. I was going up a small hill and for whatever reason there was a car stopped right at the top that I couldn't see. So the car slammed the breaks while I was in the middle of swerving out of the way. Which caused me to swerve more than I had intended. After I regained control it removed the breaks and attempted to return to the 80mph I was at previously which caused more problems because I wasn't ready for that. I am now of the opinion that a car should never under any circumstance drive for you. If a car has cruise control it should cruise control you into a wall. That I can at least anticipate.
- rustcleaner 1y agoYes, YES! Exactly! I'm hanging onto a couple older cars now because the new stuff is terrible!
- cryptonector 1y agoThis happened to me a couple of years ago where the car I was driving decided that one of those water-filled tanks ahead of a barrier on a road under construction was in front of the car just because the road was curving hard to the right. It was very scary. It almost caused an accident by itself. I don't remember how the brake assist cleared, but the fact that there's nothing one can do to make the computer not break is very scary.
- raxxorraxor 1y agoThat happens decently often. This is the reality for all systems aside from braking system in trucks perhaps, which are more sophisticated. The decision to do an emergency break is the same problem fully self-driving cars need. You need to interpret sensory input and have a model of the environment. Ironically some genius made these systems mandatory despite them being a safety concern. Granted, they tend to work if someone really falls asleep behind the wheel.
- 71bw 1y agoNever had this happen in an EU-spec 2020 Audi A4.
- hedora 1y agoThis subthread is about ISO standards. The implementation quality of the new safety systems varies wildly. On one of our cars, it is fine. On the other, it’s so bad they should have to buyback the last N years of vehicles. I hear the same high-variance story from friends. The standards for this stuff are completely inadequate.
