Disclaimer: I'm not a professional or even amateur engineer, so this is all speculation - please correct me where appropriate.



Now, I was actually thinking about something along these lines, but maybe a little bit more radical, based on the question: why can motorcycles with tiny contact patches generate such relatively high cornering loads when compared to cars with no aerodynamics?



I think that it really has to do with weight distribution; i.e., the weight on bikes when they are leaned effectively moves low and inside, pushing the contact patch, which is outside, pretty optimally. For a similar reason, I believe, the weirdo 911 weight distribution actually enables marginally superior braking performance when compared to cars where the engine is somewhere else (the 911 can use more of its rear brakes, I believe, as there is a heavy weight sitting right on top of the rear axle so it's not unloaded as much under braking).



Anyway, back to my point - consider a 4 wheel vehicle (bear with me) and a central pod similar to the 3-wheel abomination from that website that effectively moves the weight over the inside wheels via either a lean or shift corresponding with the acceleration of the turn. This would effectively move the weight over the inside 2 wheels and provide incremental usage of their grip. The tires could either lean or not - I haven't thought through the engineering.



The upshot is that the physics suggest that the weight of a vehicle needs to be in different places to optimize different characteristics: far back for braking, forward for accleration, and centered, low and inside for cornering.



Anyway, kind of a random post and probably too long, but it's an interesting idea.



That guy's trike I don't like because it's not radical enough.

It looks like it's tumbling down a hill just going around a corner.



I'm sure in Europe they're trying to design smaller cars, but you can make a 4-wheeler pretty small without the excess engineering needed to make a 3-wheeler. It's pointless, unless that's the point!

If motorcycles are about freedom, the Carver is about bondage.



Carver: The answer to a rhetorical question from a five year old.



Carver: For those special times when you want to wear a beanie and no pants.



If your wife won't let you get a motorcycle, show your manly side by getting a Carver behind her back! You'll show her!!

Bucky Fuller pulled this stunt in the forties. Unfortunately, a couple perspective backers were killed in a test drive (the Buckster was known to have a lead foot). I'm with the, It's a car, contingent. Wonder what ever happened to the GyroCar: two wheels, with a large-enough gyroscope to keep it upright, while standing still (Holy Popular Mechanics). Always thought those things would be great for rural letter-carriers. I'm afraid the Carver is more Hoo****y than Harley.

Keep thinking, inventors are rarely engineers.

Default I like it! I like it! Here's some more...

If you liked the AMC Pacer, you'll love the Carver.



Dorks of the world rejoice, the Carver has arrived.



AP News: Company officials announced today that the Carver will be unveiled to the American public in Roswell NM. Rumor has it that a roll of aluminium foil, and origomi lessons, will be included with each purchase.
