I wouldn't say that any personal car is good for the environment and probably never will be, certainly not in comparison to public transport. But the information at hand shows that local air and noise pollution is less - city centres will benefit and save money on treating asthma and various diseases caused by NO2. As renewables develop and electricity production advances, it will become more sustainable and far cleaner than fossil fuels.
My personal belief is that as batteries develop, electric is the future - the investment in diesel and petrol as moving forward, has dried up right now. The arguments against can all be countered - battery leasing resolves charging problems, but the majority can charge if necessary. Long journeys and heavy transport will be a problem, but the next generations of battery will resolve this.
Of course, there's periods of flat-lining in sales and tech moves forwards, but these problems are what helps companies find new solutions. It's like when mobiles came in the nineties, but landlines continued until the late 2000s as some resisted.. but efficiency, convenience and coverage eventually won over.
I completely accept that they're not good for all, right now and maybe for the next decade... But it's happening ;
you have totally missed the point…a normal car is not promoting itself as environmental hero, a better alternative for the planet like electric cars position themselves….which is bullshit…it’s marketing…it’s no better for the planet…where do the electricity come from? Minerals for the battery etc etc etc
