The subsidy for EVs was already large over the lifetime of a vehicle, Seymour said.
"The driver of a Toyota Corolla that travels 200,000km at 8L/100km will pay approximately $15,888 of fuel tax over its lifetime (99.3c/L x 8L/100km x 200,000km)."

Seymour also believed shifting to an EV would not actually reduce total emissions, because they would not use carbon credits under the ETS.
"They actually free up credits for someone else to use. This is because the total number of credits available is capped under the ETS."
Seymour said the Green Party should ask why it was prepared to tax people who drove cheap, reliable cars, "just so the well-off environmental wing can buy a Tesla."
"The Government needs to drop its ad hoc bans, regulation, taxes and subsidies in tackling climate change. The ETS is the most cost-effective tool we have for reducing emissions."
