I genuinely don't understand what role lane centering serves if you really do keep your hands on the wheel and eyes on the road. It doesn't steer the car if you're steering the car yourself, not when I drove cars that had it. What am I missing? The only point of cruise control is to take your foot off the peddle and to zone out and stop paying attention to how fast you're going. This is already Not Great to have in cars, but adding the same to the steering wheel, making drivers feel emboldened to look away, is probably a big part of the reason so many cars on the road today seem like they're being driven by deranged psychopaths; the drivers are actually tuned out doing other shit!
