Stupid Fear of the Day

Whenever I'm turning out of a driveway into a road, I always have vague worries about what would happen if a car were to come along doing 500mph while I was entering the road. Cars at 50mph, I can sort of see coming, and I know not to go when they're within a certain distance. But, even doing my best to look farther down the road, I just can't see ten times that far, which means that if one of those super-fast rocket-cars with a drag chute for brakes were to come around the bend, I'd be toast.
