An idea whose time has come -

Thanks to 'Uncle Ron' in South Carolina for sending me a link to this one and it is a slick idea.

However, today's 'Question Everything' is: "How do we get out if our car is T-boned by another in an intersection?" My other question, if I'm allowed two of them, is:"Does this have an electrical interlock to prevent moving the car with a door open?"

( And what about the side-impact air bags?)

Have I just described why you can't find one in your local showroom yet?
