4. Zipping down a crowded sidewalk at racing speeds
Even though it’s technically against the rules in some places (including D.C.), I don’t oppose people who choose to bike on the sidewalk. In fact, I think it’s a great alternative for people who aren’t in shape enough to keep up with traffic, and I don’t blame them for trying to keep themselves and others safe. But that doesn’t mean it’s okay to race down the sidewalk as if all pedestrian traffic ought to dive out of your way. If you’re on the sidewalk, be prepared to pedal along at a walking pace until there’s enough space to get around people comfortably (don’t squeeze them), and then when you do pass, give them a ding of your bell or a toot of your whistle first so they’re not startled when a bike appears next to them.
I don’t care that it wicks off moisture or keeps you warm on chilly mornings or makes you more aerodynamic or never gets tangled in your gears. We do not need to see your balls. Put on a pair of basketball shorts.
