The driving elephant in the room

[paranoid airbag]

I keep hearing of ways to protect other people from motorists, but is it time to ban them for their own good and everyone else's? No one wants to ban a mode of transport, but given in most major cities a segway is faster, and google's already made a car that doesn't need a motorist, have they had their day? I've clearly made my mind up but just don't want to appear bigoted. What are the pros and cons of this idea?
