Ford has patented an invention that allows you to turn the back wheel in to a motor bike.
The patent imagines a situation where you’d pull over (or park), lift the vehicle with the help of its automatic jack, remove the tire, and get everything else you need — seat, handlebars, motor, etc. — from the trunk.
Alternatively, you could just take a fold-up electric bike with you. That way, if someone nicks your bike, you’ve still got a functioning car…
I mean, seriously.
