I had a similar situation happen to me. Pulled out of the garage only to realize I had left the interior door open. Pulled back in, put it in park and hopped out. Unfortunately I put it in reverse and was dragged by the car while I tried to push on the brake. It was only stopped by the center section between the two garage doors. I was between the truck and center section.

Ever since then, I've used the e brake.
