My Car Beeped at Me When Another Car Had Turn Signal On

[ZeApelido]

On a surface street, someone next to me had their signal on and wanted to get into my lane. My car started beeping and highlighted that car on the UI. I've never seen anything like this before. Is this a known feature?

Are you sure they weren’t encroaching on your lane? Really doubtful AP (of any feature level) can ID and object to blinking lights like that.

Love it if it could... great reminder of cars about to jump in! What firmware, for the heck of it?

The beeping would suggest side collision avoidance had activated. Moving or stopped? AP or manual driving? Did your car try to steer away from the other car?

I also haven't seen the car respond to just a turn signal. But it will respond to some encroaching cars. It seems to have a hard time with cars that are very close to the front, either a very short distance or overlapping a bit. Kind of like the B-pillar cameras are not active yet.

Yeah, I guess they probably were just encroaching. I mean they were on the edge of their lane, not too close. But that likely makes more sense. But being stopped, manual driving, this was something I hadn't seen before.

I had something similar happen today. While going 25 on a city street, the car in front of me turned it's right turn signal on. Suddenly the car was highlighted on my X's display and started auto braking seemingly before the car in front started to slow. It sure seemed to detect the turn signal.

What firmware are you on?

Part of what is strange is several other cars did the same maneuver, turning on their turn signal and then turning off the road. Only this once occurence triggered the car.

It's like they have a mind of their own.

That's the lane encroachment "enhancement" that they talked about recently training and deploying back at the autonomy / investor day thing. I find it pretty annoying, tracking cars perfectly centered in the lane next to me, not weaving, etc., but my car brakes and refuses to pass them.

It's warning you to speed up and not let that punk cut you off

If a car in front of me suddenly slows down, my car sets off a LOUD and very obnoxious collision alert warning. I leave this feature on because maybe some day I won't notice and it will alert me. I wonder if the OP's car was reacting to a sudden slowing of the other car rather than the turn signal?
