Interesting, I didn´t know that. Thanks for pointing it out. However you are not cornered under the car. Maybe the strategy could be worth it if it is not easy for the bear to get under the car while you are very fast. This way you could actually decoy the bear under the car and exit on the other side trapping it for a while in order to gain a little extra time to unlock the door or run elswhere. Maybe the bear woudn´t fit in under the car at all while you could. But this is just plain theory and noone knows if it could be performed under the stress at all. It also depends how much space is under a certain car.
