But I mean, it's not about enjoying driving. It's about being an attentive and safe driver. One of the things my Driver's Ed class went over is that: Even if you are the victim of an accident, there's a decent chance that there is something you could have done to avoid it. Things like: Making sure you have 2 of your 4 directions clear, leaving extra space, and watching other drivers.
I think you're wrong that GPS reduce your cognitive load. It reduces it in the short term, but in the long term you are always listening to and referencing an noisey/bright device. In the long run it's a tax, and so it hurts your ability to be an overwhelming safe driver. This is an N=1, but I'm 30, and I'm a bit of a fast driver, and I've never been in an accident.
