Or you could just lock your darn doors.
Phew, now that we've gotten that out of the way, we can enjoy the absolute comedy gold of the moment this family of tourists learned this very lesson. They must have something tasty in there because the bear walks up and opens the car door just as calmly as if they had beckoned him over and offered him a ride to Jellystone. The bear looks so nonplussed by the whole thing that we're surprised he didn't jump when the entire family begins screaming at once.
See the whole video below, and really, give that bear car-door-handle thing a good thinking-over, and then send the designs to Distinctly Montana. We'll be happy to split the patent with you.
