I have read a lot of interesting responses and I've given this some thought.
I just cannot see how jumping out of a moving vehicle is conducive to long life. Even at low speed you are likely to have serious injuries, not to mention, what does your vehicle do when you leave the driver seat and no one is in control of it. What if it hits a kid!
I also do not agree with the act of intentionally crashing your vehicle into a stationary object, or another vehicle, parked or not. You are just as likely to injure or incapacitate yourself as you are the BG.
As an added bonus, you run the risk of injuring another person in the other vehicle...what if it's a sleeping baby and her mother?!
I like the idea of escaping the vehicle as soon as the BG gets in. Perhaps a training program of quickly exiting a vehicle would be beneficial.
