I like the cheap, easy-rolling tires. The control system will have to anticipate the difference between a quick turn and and a quick lane change, and learn to countersteer to achieve a safely rapid roll rate. In running ball sports, the path of the footprints is wider than the path of the center of gravity to force quick turns, but we learn to calculate that as children, and are challenged to explain it to a computer, especially without advance notice of intent.

He puts two wheels in the front and one in the back. This is the preferred system, not the reverse that is more prone to flip in a turn.

I immediately see two rather substantial issues: 1: the overhang is lean dependent - you can foresee the driver encountering a declining radius corner, the vehicle increasing its lean - and the driver having his head taken off by an oncoming lorry... 2: any rapid-rate transition from left-right will see the cabin (and more importantly the riders head) utilise a convoluted rotational acceleration which will likely induce motion sickness in a good proportion of drivers/passengers
I suggest we rename the vehicle as the `Next Gen Vomit Comet`...

@snave - The issue you describe with a persons head being in the other lane is a problem motorcyclists all have to account for. When you are on the outside lane of the corner and following the outside, inside, outside route training calls for your head is in the oncoming lane if you corner too quickly. I've nearly been the lorry in your scenario a few times while coming around a corner to see a helmet in my lane... I ride as well so I can say it is an exhilarating feeling leaning deep into a corner, but to pull it off you have to account for the lean and imagine yourself laid sideways while on the bike, then leave that much room inside the corner. Otherwise you're likely to finish the corner shorter than you went in.

This should be a lot of fun on a closed, safe racetrack. On the open road this dangerous toy relieves surrounding traffic, like buses, of the inconvenience of actually running over the rider. The rider will put themselves under passing buses, cars, trucks, normal motorcycles, etc. This should be a real hit with anyone who been dying to have their heads just inches from the pavement whilst racing around curves at an unsafe speed.

Ahh, how I love thee, internet. So many positive comments.

Yes, leaning a 2 wheeler also moves your head out into a different line than the wheels, but most riders, I would guess, do not corner that radically. My first thought was along the same as "snave" except I pictured my head suddenly encountering a roadside mailbox!

The tilting train idea has already been exploited:

and this innovative design can not improve the existing technology as far as I can see, as the overlap with onrushing trains on the other lane would be deleterious (like the bike-lorry example).

I like it. A lot.

Not quite a new idea.. Google the Carver One.
