It is indeed possible to jump a gap in the road. But you do need an upslope in the road prior to the gap, or a lower surface on the landing side for that to happen of course. Haven't you ever heard of, or seen, cars or motorcycles jump over rows of other cars? They use ramps....

Thanks for including number 1 by the way. I can't tell you how many people I've tried to explain that to who simply don't believe it, and like poster number 38 pointed out, such a belief is hazardous to life, or at least to not being paralyzed. Now if there is a fire that you can't put out, feel free to be a hero and drag somebody out of the car. Nobody will explode if you don't, but they will be burnt to a crisp.

Another physics one I've read about, but am too lazy to google for, is bullets shot into the water. My understanding is that if you are at least a foot under water you can't be shot. The water effectively acts as a wall and radically slows the bullet down to at least below penetrating force. If I'm right then the opening scene of Saving Private ryan is in part BS, which would be sad if true since it is an amazing several minutes overall til they finish their initial combat. I hope this is true and not yet another misuderstanding though, so don't try this at home kids....
