It probably won't happen even if you lived near the equator and had year round perfect weather. There is about 1000W/m^2^ to work with as a theoretical limit, and it's just not enough to power a car with the panels on its own roof. Not unless you keep the motor power to e-bike levels, but with way worse weight and aerodynamic cross section.

At best, it can be a supplementary power source. It needs to be low weight and low cost for even that to be worthwhile.
