I've had 5 times where I'm stopped in a car at a light or making a turn and I happen to glance in the rear view mirror to see someone barreling down on me at about 55 MPH and about 15 yards behind me. And I'm only 34.
once the guy swerved and hit someone else, I did not have a seatbelt on, I would have died if he hit me. the lady he hit, looked shaken up but OK. 3 times the guys behind me swerved away and zoomed past me ( no where near enough time to break) and missed me and missed other cars around too. one time I saw the guy coming and hit the gas and took off and the extra space I created gave him time to come to a screeching halt.
on the roads you gotta dodge people driving like nutballs, driver on drugs and drunk drivers. at rush hour people driving to or from work are the worst. their not drunk, just in a huge friggin hurry for some reason. its really dangerous on the roads.
flying is OK.
