OK, we can solve that with a HUD. How does that relate to cruise control?
It's already solved. There's no reason to keep the human in the loop for speed control. None.
So you've now got to find the cruise control cancel, possibly in an unforeseen emergency.
I drive with my left foot on the brake and right foot on the accelerator at all times. I don't even know where the cruise control cancel is, frankly said. I never use it.
False [nih.gov]. Learn to internet, bro.
I don't care about results with people who drive with their feet off the pedals, as is usually done with CC, and when they are not in a learned, trained and periodically tested external scan pattern at all times. I've learned to treat the road out there as if everyone was hostile and unpredictable. It pays dividends :)
I've also yet to see a simulator that provides anything remotely approaching the experience of driving a real car. Usually, all sorts of minor and important things are wrong. Contrast and luminance isn't what you normally get, the display gains are wrong (the image doesn't move the same visual angle as the simulated car does), etc. Every time I drove in high-end simulators, I had to readapt to driving in the real world. I'd tend to think that such studies, when done on real drivers who then have to get in their own car and drive home, are actually dangerous and subject to too little IRB scrutiny.
