car blind

When someone can't tell the difference between a normal everyday car and a nicer, more expensive car just by looking

Friend: you like my car?
Me: ya it's cool
Friend: it's a GT-R...
Me: oh it's a nicer car!
Friend:you couldn't tell by looking
Me: sorry I'm car blind...

car blind

Being unable to see the true cost of cars to society and the environment.

My alder is so car blind he can't see how much space we give up for cars in this city.
