I was coming out of a shop, walking towards Miss Pug.
Took note of a nice china blue 306 estate. A lady (daughter) was getting a wheelchair out the back of it for her elderly mother in the passenger seat.
I carried on walking. My back towards this 306 and people.
I heard a car rev, then followed by a blood curdling scream and then followed by a BANG.
I instinctively walked back to see if everyone was OK.
I heard a man run over to the fiat bravo (the car that revved) and shouted 'DO NOT MOVE IT, STOP IT RIGHT NOW, I CAN MOVE IT FOR YOU, LEAVE IT RIGHT THERE''
I then realized the red bravo had an elderly driver who thought she'd put the car into forward drive but instead carried on reversing, running those two innocent people over.
For some reason she had then put it in forward drive and was going to move forward - which would of run the people over again

I didn't hang around too long, it was giving me goose bumps. Air ambulance and police were quickly on the scene, and a chap in a RAF uniform was already on the phone to call them when I had walked back to see.
I am physically in shock as to what I witnessed today, my second sons 7th birthday.
I hope the lady with the 306 and her Mother are ok.
Absolutely horrific.
I think elderly drivers should have regular tests to check their awareness on things like this - it's putting lives in danger.
