It may not happen immediately but from time to time maybe electricity will be probably be put to use more than those using petroleum. As the years passes by, most of these oil reserves might be depleted. There are more power generators now using renewable energy sources that is being converted into electricity. This could be a signal for electric cars to be built in the near future. May be not immediately today.
I agree with you. It is not the fast change but I believe that it will finally happen. One day the situation in the atmosphere will be that bad and people will have no choice
