Auto Auto: Stay in Your Lane!
Meanwhile, back in 2018, a few automatic car features, like adaptive cruise control, have crept into the mainstream and work reasonably well, if the driver remembers when they are on and when not. Another one, automatic lane keeping, seems to really suck.
I have one of these vehicles, and have test driven a number of different brands, and, so far as I can tell, none of them work very well. That opinion seems to be widely shared. Among other problems, they seem to fail utterly at keeping one in the center of one's lane. Instead, they tend to wander until they get close to a lane boundary and then turns sharply enough to send the car careering toward the opposite lane boundary. And that's just when they happen to recognize lane boundaries at all. Of course they get confused when lane boundaries are missing or vague, but quite often they just seem to ignore them. I can't understand why this particular problem seems to be rocket science. It should be a very elementary exercise in control theory.
