Funnily enough I was told of another "incident" in Lidl car park on Friday...
Shopping done, boot loaded, lady driving, gent in passenger seat. Car is an automatic, handbrake is a footbrake..
Getting in lady puts handbag between seat and door, starts up sets off .. the beep beep goes off and dashboard warning says door is not closed properly. She opens the door to slam it and handbag falls out, everything everywhere including mobile phone heading towards rear wheels, the car is going slowly of course.
Out she jumps to save contents of handbag leaving hubby without any way of stopping car, heading under autopower towards the rear upward slope... "handbrake" not available and the drive system won't let you change from drive to park or even neutral whilst running.. panic, a great deal of shouting and afterwards all is great and nothing or no one hurt...
I said they should go down to ask for a copy of the CCTV camera, it would make a fortune on Harry Enfield or somesuch
