We can and should be allowed to drive faster on our freeways and motorways; but don’t think governments will let it happen overnight.

    The 80 kph rule of thumb is actually part of the design parameters of most regular cars. They are built to be most fuel efficient at 80 (or probably more accurately aerodynamic designed for 80).

    I was using exponential colloquially (and fair cop given its usage during Covid), but I think you’re just using cubic as a rough guide also due to air resistance. I’d note there are no extra gears at the higher speeds, so you’re probably less efficient on the tyres etc.

      And cubic just means an exponent of 3, which is one kind of exponential relation.

        No, exponential is Nx, polynomial growth takes the form xN, and in the case of a cubic, N is 3. Exponential functions tend to grow much, much faster than polynomial ones.
