Lots of NYC bike lanes are close to unusable because of people double-parking there (and numerous other obstructions). I'd love to see the double-parkers get community service, but I doubt they even get a ticket.

In some cases, I actually avoid streets with bike lanes because it's nerve-wracking to deal with dozens of double-parked cars and worry about getting ticketed at the same time.

It will be interesting to see what happens with bike share.
