One of the "issues" with the EPA emission certification test, which is used to determine EPA fuel economy numbers is that all manual transmission cars must shift at the same speed, so a Ferrari Enzo has to shift 1-2, 2-3, etc. at the same speed as a Honda Civic.

It was VW that convinced the EPA to allow the operator to shift per the on-dash shift light, which resulted in better economy numbers, and some other manufacturers followed suit.

Corvettes, going back at least to the first C5 have a "skip shift" feature that automatically selects fourth on the 1-2 shift if shift speed and throttle opening are in a certain range, which corresponds to the EPA driving cycle. It's a PIA in normal driving, so most owners learn to drive around it by shifting 1-2 early or late or buy a shorting plug to disable it.
