What happened to the driverless cars?

Nothing, I see them all the time down here. Its only when I pull up along side that I see some short old person looking thru the steering wheel that I realize that someone is in the car.

They crashed

Nothing they are at their infant stage right now, we will be using them in 50 years or so they say

Turns out stupid human drivers can come up with even stupider ideas.

They still have drivers in them yet.

They are being replaced by drone cars ...maybe

They're not ready yet. People are jumping the gun.
