The reason that EVs are not popular is that they are too expensive, experience a high rate of depreciation due to battery life, high insurance and skepticism about availability/time taken recharging battery when needed.
At this stage only select middle class buyers can afford them and Governments are hesitant about subsidising them because of it being seen as middle class welfare & the loss of Government revenue from petroleum taxes.
IMO once EVs come down to the price of ICEs, we'll see them gaining market traction. Lets face it, EVs have to pay their way to maintain roads , infrastructure etc and that means paying at least $2K P/A above and beyond battery charging costs.
The average car travels 25,000 kms a year and uses on average 2000 litres of petroleum which yields the government at least $1500 p/a in taxes.The other $500 is paid by oil companies and associated petroleum distributors & retailers, IMO.
