Some pretty rabid anti-cyclists about here.
As someone who tends to cycle 9 miles each way to-from work most days (and then spend the rest of the time either driving or cycling at work) along some pretty busy roads I have to say car drivers need to remember they aren't the only people using the road. I've almost been wiped out by one driver who completely ignored the road markings and the cyclist in high-viz clothing who was actually cycling in the correct lane.
Personally I think its a great idea. It gets people active and the more cyclists about the more general motorists will have to get used to them instead of screaming past shouting obscenities for them daring to use the same road as their crappy knackered corsa.
