1) Our roads aren't wide enough to safely support cyclists. When we overtake we're forced to use the wrong side of the road.
That's called overtaking
2) Cyclists don't pay road tax.
Yawn Yawn
3) Most can't cycle in a straight line.
Very true , I see wobblers all the time
4) A lot don't wear any helmets
Again very true .
5) Cyclists don't have to obey the Highway Code.
Some do , some are knobbers and think they don't have to ,, so Yes very true
6) Cyclists have no insurance so if a cyclist damages a car the owner will likely have no compensation.
Most don't so yes very true
7) Some cycle double-abreast, creating an even greater hazard.
Wish I was double abreasted
8) They are a danger to themselves and drivers as they can't keep up with a decent road speed. If a car was caught by Police travelling at a cycle's speed the driver would be fined for obstructing others and/or dangerous driving.
Looking at one of the other threads, the police will all be to busy arresting web site owners for publishing times after sportives, so no worries there then
