Car brain

Derogatory term for vehicle drivers, whose cognitive functions have been impaired by the act of driving.

Long term dependency on their car has caused their brain to atrophy to such an extent that they barely recognize pedestrians as human. The car brain will speed in parking lots where they share right-of-way with pedestrians, will block the entirety of a crosswalk while waiting for the green light, overtake bikes without giving enough room, splash pedestrians with water by hitting puddles at full speed, et cetera
Look at that, some car brain parked in the bike lane. Sure would be a shame if someone keyed them.

brain ninja
