I feel you have made some very interesting points Bernard. As we have experienced with diesel cars, the wind can change rather quickly.
"I can see it working in boats, trucks, agricultural big machines etc, but passenger cars will be battery electric powered and that is it."
I would add to your prediction that there will be a half-way house for many people, using Plug-in Hybrids. I suggest this is not a good time to buy a new car with any certainty. Budget constraints, for most people, prevent them even considering an electric or plug-in hybrid.
If you can afford a new, or nearly new, car it is not a straightforward choice. I decided to stick with what I know, time will tell if it was the right decision.
