I was thinking about going on dragon's den with an invention. On each corner of a car, their would be little lights. When a driver wants to turn a corner, a light would go off. Say, the driver wants to turn left, the left light would flash. Right, the right light would flash, and turn itself off once the manoevre has taken place. Sounds ridiculous, I know, it's never going to happen, especially at things called roundabouts.
Maybe we could get our heads together and think about something compact, perhaps in a spray can? That one could spray ice off from icy windows, or a little scraper that could wipe snow from a window?
Oooooh, it winds me up so much lozzer50, don't even get me started!
