All very good points. I agree that a car will be faster than a bike around a corner.
In the end, the concept, either Carver like or Benz like, is a gimic.
From my point of view the positives of aerodynamic efficiency, reduced gas consumption, and ease of making it a hybrid or all electric vehicle are what attract me. Not saying that the concept would be better than a car (maybe aerodynamically and weight wise tho).
The term "tilt-steer" was coined by someone else, not me.
The nature of the concept does force you to add complexity to the suspension and steering system so I also see the issue with that.
In the Carver concept this would be a big issue (i.e. is the tilting mechanism fails, the car will not turn at all). A take on the Benz concept, with the addition of steering on the front wheels at low speed in the urban environment, could result in a safe system even after loss of the "active tilting mechanism. Possibly solving that safety issue?
Greg, I know you are very knowledgeable about vehicles in general, much more than me. Any comments on the Benz style vehicle? The Carver? I am just interested in what you have to say past the upfront safety issues.
