Easier than you might think.
Someone said that good judgment comes from experience -- which in turn comes from bad judgment.
Scenerio:
16 yrs. old, license <6 months, roadway 4ft. above a pond, 1962 Pontiac station wagon (with rusty (holed) floorboards).
I was able to unbuckle my seat belt, roll down my window& exit the vehicle. As I swam past the rear of the car, I realized it was still running, I was able to return to the front, reach in, turn off the car &retreive my keys. I then swam to shore (~ 100 ft.) & watch it sink. It takes longer for a car to sink than you would think.:o <img src="/images/graemlins/blush.gif" alt="" />
Prolouge:
We retrieved the car after ~4 hrs. We drained the crankcase & tranny & replaced the fluids. We salvaged 1/2 a tank of gas. The car ran for years ( a little musty on humid days).
