What are the odds of this?

An accident where NEITHER vehicle has a driver?

Today I took Brylee to Toys R Us because my friend's child just turned 2 and we were buying her a birthday present.  After spending an hour in the store (Brylee liked touching all of the stuffed animals, etc...) we buy our gift and leave.  Well, as we're walking to our vehicle, I notice a girl in workout gear go running by us.  I don't think much about it, and I lean with Brylee on the back of our SUV while I dig my keys out, etc...  I put Brylee in her car seat, and I had just strapped her in and go around to the driver's side door, and there's a "BAM."  Our vehicle was kissed (literally, there is red lipstick on our bumper to prove it =) ) by an EMPTY car going backwards across the parking lot!!!

It turns out her car is a stick shift, so it was still in neutral when she parked it.  And I guess if a stick shift is in neutral and has any amount of incline to work with... well, it can drive itself!
