In proof that violent jerks are multi-modal, NBC 4 reports that a motorist was stabbed by a cyclist last night after an altercation near Scott Circle:

D.C. police officers were called to the 1600 block of Massachusetts Avenue NW about 10:20 p.m. Wednesday for a report of a stabbing. Witnesses told investigators that a bicyclist struck the driver’s side mirror of a Smart car with a heavy bike lock.

According to the police report, the driver then got out of the car and asked, “Why did you do that?”

That’s when it escalated into a fight, which ended, according to witnesses, when the bicyclist stabbed the driver in the ribs and fled the scene.

Before we jump into the usual “Cyclists vs. Motorists” narrative, let’s note that a stabbing happened. Carrying a knife and using it during a heated argument is generally a sign that we’ve got more to worry about with that person than their mode of personal conveyance.
