And I say this having grown up my entire life without a car, biking everywhere. I'd take tickets for riding on the sidewalk, and I'll do it every single day I ride. Sharing a road with 2500lb vehicles that go 2-5x my speed is unsafe and all the talking and lane marking in the world will never undo that fact. Nevermind how utterly anti-social and rude you must be to bike in a lane 20mph under the speed limit.
I spend as much time as possible in the Netherlands since they seem to be about the only sane country when it comes to mixed-mode transportation and not trying to murder people while doing so.
