That comes in at an additional 400lbs on a vehicle that weighs 6,670 lbs if you assume the maximal weight of the panels and the need for a metal roof anyways. That extra 6% weight just doesn’t matter. 6% losses range for 12% free charging seems like a worthy tradeoff to me. (and again, this is the maximal value).
Yes, but mini vans aren’t lifted 20 ft off the ground with absurdly huge hoods for no apparent reason.
The reason trucks and SUVs are killing kids is because you can see a 4ft tall person that isn’t standing 100 yards in front. These are the only vehicles with this problem.
