I like the compromise.

Plug-in hybrids with reasonable range (let's say 40 miles) achieve 99% emissions reductions. But don't have to lug around 1000 pounds of battery.

Allowing for plug-in hybrids outright would have been a good idea. Allowing only e-fuels is a second best.

Problem is that companies are buying those for tax advantage, and never charge, so CO2 emissions are higher - additional weight of the battery.

There was report somewhere, that often such vehicles are never charged.
