That's how much mileage you'd get from the solar panels, if the car was in the sun the whole time. {{x|Would be less if the car is sometimes parked under trees, between tall buildings, or in a garage.}}

The average person drives more than that, so the car would still need some external charging. Solar options include [[rooftop solar|rooftops]], [[solar charging stations]], or maybe a [[rooftop_solar/gas_stations|gas station roof]].

Other considerations: In the winter, one would need to brush snow & ice off ''all'' parts of the car, not just its windows/windshields.
