Hazards

Just thought I would share an irritation
Will the person who invented hazard warning lights for cars and other vehicles please stand up so I can kick them squarely where it hurts.
So far as I can see hazard warning lights should be on and flashing all the time with some drivers as the hazard they have identified clearly sits behind the steering wheel...
These lights are put on a vehicle for use in extreme conditions such as breaking down on a dark and unlit country road or a seized engine on the M4 motorway when coming to a sudden and jolting halt.
Not for mums who ignore all traffic signs and road markings to pick up the fruit of their loins from Nursery School or if it suddenly starts to rain and  the car in front has suddenly slowed down - this is supposed to be expected and sure enough if it is raining on your car then it really is a given that it is likely to be raining on the car behind you.
Hazard warning lights are not to be used to let your other half out at the crossing so she or he can stumble a little closer to the shops. Funnily enough on a clear day I can bloody well see you doing stupid things one of which is drawing attention to your stupidity by putting on flashing lights.
Stop it for gods sake...
I may just decide to drive into you just because of them. on that subject of purposeful accidents don't those little signs in the back windows of cars stating the fact that a little person is on board just make you want to speed up and drive like a maniac?
