I do think it will happen and that it is simply a matter of time, at least in Europe, many countries are implementing laws that will more or less ban any new ICE cars from being sold around 2030-2040.
Tesla is showing the way, but their cars are also very expensive at this time, I know they have the model 3, but since it has huge waiting lists etc. and the fact that we have a lot of mini cars in Europe, means that we wont see much change until all the old carmarkers get their production going.
I follow a blog called
www.electrek.co on a daily basis and it does seem like most carmarkers will be comming out with a low of new eletric cars around year 2020.
Would pesonally love to own an eletric car, happy to go with Model 3 from Tesla. The others Blot etc. still have too short range for it to be pratical. But as soon as all the carmarkers start making eletric cars in bulk, there will also be a leap in technologi and the price of batteries will be driven down. Making it more affordable for all of us.
