I have grown to love rear cameras and rear sonar...
I think the time has come for me to get them on my next car.
There's something new called lidar Prue, you should find out about that
LIDAR=Look It's Der At Rear
Saw a prang out the front of the cafe where I was having breakfast this morning - a bus tried to turn into a gap which didn't exist and sideswiped the back of a stopped van. A certain amount of gesticulation and horn-blowing followed.
At least my accident was caused by me and l can't blame anyone else - however there was still some self berating going on!
