Yesterday in the grocery store parking lot, I'd shifted into Reverse gear (dinging sound is activated) and still
couldn't get the attention of the doofus couple who'd, seconds later, blocked my right rear quarter panel with their grocery cart to unload into the car on my right. I sat there, car dinging and waiting, waiting and dinging, waiting...until I finally
had to drop my right rear window and politely ask them if I was clear - then
the guy's brain activated and he moved his cart out of the way (duh). They'd arrived behind my car just as I'd shifted into Reverse and
they were ogling her, so it should have been obvious with my reverse lights on and the dinging that I was trying to leave (there was even eye contact with the guy as I looked over my shoulder). Reverse lights & sound alerts don't necessarily equate to intelligent reception!
