Somewhat related to this thread and topic ... I'm driving a rental car right now and its the first time I've driven a car with a lane-assist feature (sensors help steer car back into lane when drifting out of lane). In France you are supposed to give 1.5m margin when passing a cyclist so I drifted left and out of my lane to pass - and really freaked out when the lane assist feature kicked in and steered me aggressively back toward the bicyclist...

I think I could have avoided this situation by turning on the left-turn signal to disable the lane-assist and generally its a good idea to use the indicator even when just passing a bike -- but that's not something I normally need to do to avoid this particular failure mode ...

That's exactly what you had to do according to the regulations.

People shouldn't drive drunk, but disabling the airbag when the driver is drunk is not acceptable.

Well, LKA would actually help to stay in lane while drunk, no?

That thing has a good default that is still overridable by the brute force (force that's less than the force needed to steer if the power assist fails altogether).

My point is that unexpected hazards when people break regulations is a problem. Because people will break regulations.

Yeah, that's the way it works on my dad's Subaru.

The adaptive cruise control in my VW actually gets confused sometimes. Drove through a puddle at the beach last year and it jammed on the brakes. Glad nobody rear-ended me.
