  1. Nice to see new ideas but this looks like rubbish. Imagine the slightest lateral G loading on that setup, can it turn at ALL without going sideways? I doubt it. Parking is not a big problem for me anyway. First and last we will see of this concept.

  2. Oiseau Denuit My idea? For those who find parallel parking such a problem which I do not: A) learn how, if you can't then you probably shouldn't be driving anyway, B) purchase a newer car with automatic parking features. Can you not see the obvious sever problems with this set up in the vid? It necessarily has thin round tread making for a relatively tiny contact patch on the road. But the main problem would seem to be extremely limited lateral load capability, dangerously so. And it's an inherent aspect of the design. It's sort of a cute but ridiculous solution to a minor problem that's already been solved in a far better and cheaper fashion. Maybe there is a place for it on some sort of machine but not on a normal car or truck. I would bet money that you will never see it on the market for autos.

  3. Walber Macedo An aside--I don't even want "runflat" tires as they compromise performance and add costs, and for what? That one or three flats per decade that I already have a good solution for? No thanks. I favor some models/yrs of smaller BMWs for example, (own an older one) they adopted runflats and initially trashed the suspension behavior then adapted the suspension to the compromised tires. Now the suspension is compromised for proper light wt. normal tires. Even if the concept in the vid did not have the fatal design flaws I mentioned above, there is for certain a big price and weight penalty to pay for those wheels. Weight is the enemy of car performance and the wheels are by far the worst place to add weight. More mechanical complexity is a negative unless well justified and the more things you try to make it do the less proficient it tends to be at any of those tasks. I want my tires to be optimized for low resistance, high G capabilities for acceleration, breaking AND cornering. And to be affordable and long lasting. That's enough to ask from tires. Have them go sideways is guaranteed to compromise all the other features. There is a darn good reason you don't see high performance road cars (or motorcycles) that are also superb off road. Inherent compromises are unavoidable. It's one or the other. Let alone a boatcar or a flying car,...that's an extremely expensive car, a very expensive plane and it will NEVER be great, if even decent, at either flying or driving. They have been attempted for 3/4 of a century only to prove that point.
