It's going to be a tricky thing for the Feds to figure out how to tax Telsas like gas cars are taxed via fuel taxes.Yes the Elio looks great if you only look at the CO2 output. I think there have been other threads addressing why Elio doesn't want to go with the Feds for financing.
It's going to be a tricky thing for the Feds to figure out how to tax Telsas like gas cars are taxed via fuel taxes. Maybe by using the "average" gas cars' taxes per mile or something, I dunno.
Also as more solar and wind power plants are built, it will slowly change the USA's CO2 per KWh output. There is also the way gasoline is produced and the waste, pollution, cost of transportation, and politics involved with that process to consider.
It's all ready in the works. It's called "Road Tax by the Mile"
