It's nice the UI shows how many miles the PV cells have added, but I doubt Aptera can come up with a better "Guess-O-Meter" (GOM) range prediction than other BEV's provide. It's impossible to predict the future, so every BEV's GOM is designed to be pessimistic.
I would prefer to know the added power in terms of kilowatt hours. I assume Aptera's engineers measure solar charging in kWh and hope they will allow drivers to select kWh instead of miles.
