I live in London and I'd love to cycle to work, but the infrastructure (for my route) just isn't there. And for people who aren't experienced cyclists, it is even worse as lack of confidence actually leads to more accidents.
Sure, some people will hate you for that, but I prefer disliked over smeared onto pavement any time of the day.
