A shameless plug for Roll Resistance...
Did you receive a little present from a concerned citizen recently? He or she may have wanted to remind you that your choice to block a bike lane was unsafe and probably illegal. Parking in, double parking in, or otherwise blocking a designated bicycle passageway forces cyclists (and others using this lane) to ride into the street, possibly blocking traffic and placing the cyclist in harm's way.
Think: car moving at 45 mph and bike moving at 10 mph. What fun! Bike lanes are there for a reason. Please be respectful in the future.
