Better stick to petrol cars I think. No power to weight ratio restrictions. No charging batteries for 1/2 an hour if a charging station can be found, and hoping no one else is using it.
How quickly do the batteries discharge if the trip to town is uphill nearly all the way? That's my predicament, uphill for 80ks, downhill coming home. Checking my petrol mileage via my liters per 100ks gauge, much more petrol is used going to town than coming home.
If I had an electric car, I probably would have to charge the battery in town so I could get back home. But what if there were motorists lined up to use the charging station? How long does it take for each car to be charged? I might be there all night waiting.
