How hard is it to LOOK in your rear view mirror to see if someone is behind you???
In a parking lot she's a bit confused, starts to back up and I lay on the horn. Nope, that doesn't stop her, nor did my car, after the initial hit, she still backed up.

Oh, it was dark enough for headlights, so she should have sen those too.
She'd no longer be breathing on this planet if my 911 was hit.
