This thread swows there are 2 groups- those who push to get to a goal quickly and may be reluctant to change their pattern and those who take their time stopping as they want. Probably electrics are not developed to the point the first group can be satisfied with them. They might want to stay with ices or wait for hydrogen to reach practically. Most of the second seem to be happy for their uses. This problem will probably show up more as Tesla pushes past the early adopter market.
