Isn't this all just a bit political, people saying what they think they should say? I do what I choose.
Part of that is I make a concerted effort to drive at 30mph in the village that I live in. People speeding through it infuriates me and every time I do 30, I end up with a long line of cars behind me. Experience tells me that most people speed in a 30!
Okay, so jumping lights on my bike will annoy some people but if I'm sat at some lights and can see 300 yards in each direction and there's no traffic coming, I see nothing wrong in carrying on.
Clearly if there's traffic about and a chance of a collision I'm not going anywhere, as I'm on a bike and will come off much worse than a dented bonnet.
I say it's personal choice.
