uhmm. you do know electric cars have just as much maintenance as a gasoline car, has just as much breakdown time as a gasoline car (especially the latter, maybe even more, as my boss has his 3 year old car just as much in the shop as I have with my 20 year old high milage cherokee.. And he has had his car stall because there was no charge left, he had to tow his car, whereas with a regular gasoline car you just get a gallon of petrol and you drive on..
And as said, not everybody has a parkingspace with an outlet at their home..
It's great if you have always have a charging point at home and at work, but even at our work, there is only 1 outlet, and guess who is charging his car there...
Yes outlets are popping up more and more, and in a decade or so, it'll certainly be everywhere, but not right now..
