The Honda civics in the 1980’s weighed around 800 or so kg as well. You know one of the reasons they got heavier? Crash ratings and safety features.

So once again I’m calling bs that they will get 45 miles out of this. Even if they got it classified as a motorcycle and scape around the car safety requirements, it still won’t get a real world 45 miles a day from solar charging. Your math will never add up to that.
