For a super efficient car your math seems about right. A gallon (~4L) of gasoline is roughly 33kW/h of energy, so 100-120 miles per gallon equivalent car is possible, but difficult (sorry for US units, that's how we measure car efficiency).

It may be good as a supplement like you said, or can possibly keep the AC running or something like that.

Just so you know, when it comes to car efficiency the UK uses miles per gallon. Petrol stations however show prices by the litre, oh and we use miles and yards for distance.

TlDR: mpg is fine to use with us.

Yeah I went off Google's estimate of electric cars tend to get 3-4 miles per kWh (which I guess will actually vary massively)

And the car panel will be less optimal as the panels will be flat. Although unlike roof panels you could potentially move the car around to stay in the sun for longer.

For me, this would actually be an ideal car. I need a car for where I live, but I only use it a couple of times a week and almost always journeys of 5-6 miles or less. I'd only need to charge the car from mains in the depths of winter!
