This week is Bike to Work Week in Washington, D.C., which is a perfect opportunity to point out why the vast majority of bikers are huge jerks who ruin the road for the rest of us. I’m not saying they’re jerks all the time; just when they’re on their bikes. Kind of like how someone turns into a Mr Hyde version of himself when he climbs into a Prius.

I’m not even saying all bikers are this awful. Just most of them. Enough of them to give bikers a bad rep, even when some of us actually try to be considerate, safe, and respectful. So this Bike to Work Week, please do bike to work — just don’t be a jerk about it.

5. Biking on the road, without following the rules of the road

You know what I’m talking about — the bikers who use the bike lane or actually drive in the traffic lanes, but breeze through stop signs without pause, creep past red lights, cross lanes when they turn, and generally act like the rest of traffic should bend around them. This is incredibly unsafe — for bikers, drivers, and pedestrians. As someone who walks to work every day here in D.C., I could count on two hands (and a few toes) the number of times I’ve nearly been run down by a bike that had no intention of stopping for a red. Hills are no excuse. If your brakes are too poor to come to a full stop when you’re pointing downhill — or your legs are too weak to stop then start again while climbing uphill — then you shouldn’t be biking on the road. Get in shape, get a tune-up, and come back when you’re ready to bike safely.
