Its also gibberish. There is a sweet spot in which engines will run 
while burning the "maximum" amount of available fuel, without producing 
extra waste products or failing to combust it. For every car 
manufactured *ever*, this is between 50-60 miles an hour (due to what 
the RPMs are at that speed). Letting a less polluting car go faster 
won't work because them moment it goes faster it starts to burn the fuel 
less efficiently, which means pumping more in, some of which doesn't 
combust, and that means a) your producing *more* pollution, and b) using 
more fuel than before. The only sort of vehicle that "could" use such a 
rule might be a hybrid, but then *only* do to the fact that the gas 
engine is "tuned" to always run at optimal RPM when operating, and the 
question because if it can generate enough current to sustain the higher 
speed while "at" that optimal RPM. If it can't, you're still not gaining 
anything.
