I'm all for reclaiming and equally sharing the roads that all of us paid for, but it can't be done by biking recklessly in the middle of car traffic. It has to achieved politically.
There's nothing reckless in cycling in traffic. If anything, some car drivers can be reckless by driving dangerously close to cyclists. Cycling on the streets is a right that we already have and that cyclists already paid for. The only thing that remains to be achieved is that a vocal minority of motorists accept this fact.
