what happens when the parking lot is full of cars?

The answer seems pretty obvious. However most of the stores around here almost never have parking lots that are more than half full. I'm actually more interested in the possibility of doing it with highways and roads. It's a long way off but interesting to think about.

I am deep into solar and wind power...my RV is totally independent of commercial power.

However, the still to be resolved question, when it comes to dependency on wind and solar, is what happens on a calm, overcast day(s) commercial electric generators, are still working, inputing to the grid, we still have to have generating capacity, that covers 100% of requirements, even if in a prefect situation where, no power is taken from the grid

Solar panels, comprising solar cells connected in series, cannot tolerate unequal lighting...so in the case where, a road was partially in the shade, then some mechanism has to be developed to control the shaded cells

Much the same applies to a parking lot...cars would shade the cells, and this, under current technology, would be a problem..
