I read the whole post - nothing in it gave me the impression that you believe CAFE rules work.
At least in the USA we are not pushing for electrics with no limits on consumption. The electricity used to power an EV is calculated into CAFE calculations based on the Petroleum-Equivalent Fuel Economy calculation (PEF) The current PEF for CAFE is 82 kWh/gal. It will change 23 kWh/gal in 2027.
Looking at CAFE numbers for the Ford F-150 as an example:
. 25.9 mpg CAFE (ICE)
. 31.2 mpg CAFE (Hybrid)
237.7 mpg CAFE (EV today)
. 67.1 mpg CAFE (EV - 2027)
Looking more at the topic of this thread - motorcycles haven't really seen an increase in fuel economy for the last 20 years - maybe more. The 2022 BMW R1250 I rented got the same MPG as my 2011 R1200 which gets the same MPG as my old 2002 R1150. The new bike is lighter and makes 40 more HP but gets the same fuel economy.
When manufacturers aren't required to make vehicles more efficient they don't.
