I think the Rockwell scale is used to measure hardness of metals. Or maybe we're talking about flying squirrels.

wonder what the gas savings would be if a car were light enough to be lifted, or at least tipped, by hand. Wondrous! There's a fairly high limit on how light you want a vehicle to be. As things stand now, a strong wind can buffet my 3700-pound station wagon. If a car really doesn't weigh very much, its stability in a crosswind is decreased.

And motorists... among them some Freepers... will still flip us the bird for having the gall to ride on THEIR roads.Well, obey the rules of the road. No tandem riding, stopping at red lights and stop signs and using turn signals. Maybe then you and others will get a little respect.

More info a
Science News The alloys are strong yet unusually elastic, so they can deform more than other alloys and still return to their original shape. Engineers can also readily mold or bend the materials at room temperature into various shapes, a property called superplasticity. The materials also possess two characteristics desirable in machine parts that experience wild fluctuations in temperature, such as those in a spacecraft. While most metals expand with any rise in temperature, the new alloys expand very little between 200°C and 300°C. Moreover, conventional alloys deform different amounts at different temperatures, but the new materials show about the same deformation whether it's 200°C or 300°C.

Well I guess that just shoots down my wishful thinking very succinctly. LOL
Crosswinds.
Forgot about wind...semi-truck suction, etc.
'Course, if these newer alloys are 'flexible' as stated, hehe, maybe they could sorta bend (?) with the wind in ways that make the wind flow over and around easily? I mean, this article indicates such metals could one day sense danger, and could possible 'heal themselves'---wild, weird and really hard to imagine.

A while back the WSJ had a big advertisement in it for a team of engineers, US ones at that, who had formulated metal foam. Now....that's cool.
Does anybody know anything about that?

I'm not an engineer, although I once wanted to be one, but wouldn't lighter, stronger alloys be useful to make the parts necessary to creat such a light-weight and strong car, while allowing us to use "lesser" metals (like old wheel weights, for example) to ballast the car down low, lowering its center of gravity, thus making it more stable? It would be a problem if the ballast could shift, but surely we could solve that problem, too. Epoxy, for example, or even rivits. Bolt-on weights would be easily removable, so maybe you could take them off, tip the car up on it's side, and work on it that way?

You'll have to compensate for lack of mass with increased velocity.

Maybe even a dynamically adjustable center of mass.
