As a driver you not only see cars. You apply theory of mind to each car, assigning a personality to each moving car, even if you can't see the driver.
Let's see you see a car full of bumps, marks and broken lights. You might think: this car has crashed before, I am going to avoid it. Or a car with racing parts and decals and tinted windows, you know that car likes to accelerate faster than usual and may be unsafe to be around. Or you see a SUV with baby on board stickers, you'll know that if you are going to crash you may try to crash that car last because it has babies inside, etc...
So humans don't see objects they see the whole situation, unconsciously even.
Is it optional? if you see a car zig zagging, or a car is going in the wrong direction, or there's a driving school sign, etc. As a human you can tell something is going on.
