I can't help but think I might be a bit too hopeful for my own good, but I do hope to god that these become well spread and used about in my lifetime. Hopping in the car to sit back, play video games on whatever handheld device I have at the time, and enjoy the ride without stressing that I could be in an accident sounds great. I mean, I love to drive as much as the next guy, but I always get nervous around towns and cities.
