And I really wish they'd stop the aggressive centering on lane merges...
What I hate most about the adaptive cruise control is when someone turns left in front of me (from the oncoming traffic). The car sees this and immediately decelerates (sometimes pretty hard) to avoid a collision that was never going to happen.
Another problem is if CC is set for the speed limit, and that car going 10mph slower suddenly changes lanes. The car starts to accelerate - and you may be heading for a red light.
I'd settle for smoother stops while using AP. Having it figure out the stopped traffic a bit late and then slam on the brakes is annoying.
These are all the things for me. Please don't make me look like a clueless driver or get me pulled over at 11PM for erratic behavior.
Or worse, get me into an accident by being unpredictable.
I think lane positioning would benefit from having a guard band, rather than what seems to be a fixed ideal position. There should be a range where the car just stays put, so it doesn't make unnecessary corrections. It can have soft edges and hard edges. Soft edges for static positioning and hard edges for emergency recovery.
Then it can bias itself from other inputs.
- Lane opens up due to merge or just because they made it that way; just sit tight.
- Car in next lane is getting cozy with the stripe; slide over the other way a little.
- Sweeping right turn coming up; ease to the left edge, slide to the right at the apex, then slip back over as it ends.
- Car changing lanes into you; go all the way to the opposite hard edge, beep like crazy, and please blow the horn as well!
Isn't all of this what human drivers do?
Then we're just left with solving the "brake like a human" part of the problem.
Like, if there's slower traffic ahead at least let up on the accelerator a bit, OK pal?
