Are you talking about electric vehicles that are similarly powerful to cars most people are driving today? If so, what are you basing this on? What are your sources?
The fastest solar powered vehicles that currently exist max out somewhere above 40mph and look like this:
I understand that charging when not in use can provide more power, but these are pretty extreme designs to optimize speed. A more normal looking car would be a lot heavier and slower. I don't see it happening, at least not without people getting used to having much less power available.
