As a supposed part of battling climate change electric cars are a bit of a joke.
I completely see the argument for them in towns to reduce pollution on the high street, but as an energy saving thing perspective is needed.
Take this for instance, culled from the Week magazine:

All but the “truly deluded” now accept we have to do something about climate change, says Damian Carrington. Trouble is, no one backs their words with meaningful action. The UK leads the world in setting CO2 targets, but look what it’s actually doing: building more roads, cutting taxes on domestic flights, scrapping a home-energy efficiency scheme. Other nations are no better. Justin Trudeau calls climate change an “existential threat”, yet owing to Canada’s tar sands exploitation, its emissions have risen since 2015. Japan is a big financier of overseas coal plants; China builds a coal-fired power station every week; Norway is developing giant new oil and gas fields. Meanwhile, companies hide behind pledges about carbon-capture technology or carbon offsets. Oil giant Chevron touts capturing and storing CO2 emissions underground as a solution, but its advertised plans look to cover less than 1% of its 2019 carbon emissions. As a result, by 2030 we’re on track to cut 2010 levels of CO2 emissions by a measly 0.5%, whereas a 45% cut is needed to avoid climate catastrophe. To achieve that we first need to cut the “bullshit”.
