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.

Car Brain 

A phrase commonly used by urbanists who think choosing to drive means you have a disfunctional brain, and that all drivers are insonsiderste assholes who go 90 across parking lots, randomly swerve into bike lanes, and go out of their way to run over pedestrians in crosswalks... because obviously if you put all the asshole drivers on a bike, bus or train instead, they'd suddenly become more considerate.

Urbanist: I was cycling the other day and almost got hit by some car brain going 30 in a 25. All drivers are assholes. We should ban cars.

Car Brain

An American living the suburbs who is incapable of thinking about getting from place to place without taking his or her car. Complains about safety on transit all the time, and opposes all "socialist" transit projects, even though it would benefit them without the carbrain needing to take action. May alsoo be a NIMBY, but not necessarily, and should not be used interchangeably.

Person 1: The subway is filled with druggies and homeless people. In my car, I'm in my own safe bubble.
Person 2: You are SUCH a fucking car brain!

carbrain

Car-centric urban planning that has led to stroads, strip malls, ugly america, and cultural disintegration. All because the idea of taking a light rail to work fills them with panic and heart palpitations.

This NIMBY carbrain wants to choke younger generations with crippling debt rather than take a light rail to work.

Carbrain

A boomer living in suburbia who incapable of thinking of getting around without his or her car and is deathly afraid of public transit, biking, walking, or other viable alternatives to driving. Complains about speed and safety of public transit all the time, and opposes all "communist" transit projects, even if it speeds up traffic. May also be a NIMBY, but not necessarily.

Person 1: The Metro is filled with druggies and homeless people. In my car, I'm in my safe bubble where I am 100% safe and no one can harm me!
Person 2: You are SUCH a fucking carbrain!
