The latest to be released, at an event in Los Angeles, is a motorbike that looks straight out of Tron. It's called the Mororrad Vision Next 100, and BMW says that it's so safe that you'll be able to ride it without a helmet.
"Any late reaction from the driver will trigger and the vehicle will balance out."
What's more, it's electrically-powered, which means zero emissions (as long as your electricity comes from a zero-emissions source), and the power unit folds up like an accordion when the bike is parked.
BMW has envisioned a bionic riding suit and visor to accompany the bike, with the visor beaming augmented-reality lines and bank angles onto the road ahead, controlled by gaze-tracking.
Want to see it for yourself? The bike is on display to the public at the Barker Hangar at Santa Monica Airport. But be quick, it's only there until October 16. If you don't make it in time, here's a YouTube video to enjoy instead:
