I still don't think it would be advisable to bail out of a moving vehicle (be it a plane or car). And the reason being the speed at which you are moving. If an accident is going to be bad enough to want to bail out of it you are probably moving fairly fast. For example, you are in a car going 60 mph and about to hit another object. So you jump out the door and onto the road. This would be about the same as riding a motorcycle and laying it on it's side at 60 mph. Now a well prepared motorcycle rider is wearing a helmet and a protective suit of leather or some other material. A person bailing out of a car won't be wearing that protective gear. So he is going to get chewed up by the road severly. I'm not an EMT, but I'll bet the ones on this board can vouch for that.

I do however have some incidents that have happened to people I know that are relevant. My roomate was riding a motorcycle. He was wearing a helmet, shorts, and t-shirt. Not smart. The car in front of him came to a sudden stop. He was able to get the motorcycle stopped in time, but when he did he couldn't control it anymore. When he stopped the bike fell over on it's side, with him on it. He told me his helmet wacked the pavement pretty hard. Also the arm he landed on had some "road rash" from hitting the ground. His injuries were slight, but he was only going ZERO mph.

One time my brother was driving northbound on the freeway in a vehicle with a T-top at 70 mph. He fell asleep at the wheel, hit the outer barricade, came across the northbound lanes, ramped over the bushes in the center divider, the vehicle turned upside-down, skidded across the southbound lane, and into the ditch on the other side. He did not bail out, but because of his height (6'1") and the open top, his head came in contact with the ground. His scalp was completly rubbed away in one place until you could see a patch of his skull that was the size of a quarter. I didn't know this until I saw it but a person's scalp is actually very thick. BTW he was only in the hospital a week and is doing fine now. Although he has lots of facial scarring.

I realize that neither of these people bailed out. However, the circumstances made it close enough to hopefully illustrate my point.

Now for bailing out of aircraft. In an aircraft you will be going much faster than in a car, so whatever damage takes place will be much more severe. The only time a bail out should be condidered is if you have a parachute, enough altitude to bail out at, and the pilot tells you to. Of course this only applies to skydiving planes and military aircraft. Like I have said before, I have skydiving experience. Also, I am in the Air Force. In both areas of aviation I was trained that we do not bail out unless the pilot tells us to. He is responsible for the aircraft and his passengers. The decision to bail out is his and his alone. It is not a good idea to try and bail out of a commercial aircraft under any circumstances.
