Why is a quad bike called a quad bike

Bansturbator!

I think they look rather good fun as a matter of fact.

Very useful for farmers too.

Exactly, but not when driven by a bell end up your road they are not. Should be treated the same as a Segway!

There may have been 4 people on a quad bike but does it mean that they were actually driving dangerously?. it is amazing how the swivel eyed judgemental immediately jump to conclusions without seeing any evidence

Well your sentence actually shows they were driving dangerously, there were 4 of them on a vehicle made only for 2 which may well have contributed to the accident as it was overloaded. They also had no number plates on it so if they were on the road then once again another minus point which makes me think that it was possibly a farm vehicle so could quite well have broken, missing or no lights at all. Don't jump to conclusions...
