It sounds as if you really think it's a good idea to stick with imperial. In your opinion is this a common attitude within the technologically sophisticated section of US society? I didn't think it was but maybe I am mistaken.

I prefer metric, from a policy perspective, I just think the path dependence has too strong a case to revamp industrial toolchains. (Changing the road signs and temperatures, by contrast, is both trivial and useless.)

Other things which are better that we'll probably never have include broader gauge railways, Dvorak for everyone, Wankel engines, and Betamax (vs VHS).
