Weird, I want to get one since I am adding solar panels (already bought them) to my tiny house and thus I can charge the car for free. Why pay for gas at $1.26

Weird, I want to get one since I am adding solar panels (already bought them) to my tiny house and thus I can charge the car for free. Why pay for gas at $1.26 CND a liter? 1.26*3.8=$4.788/1.30=$3.68 a gallon in the US.
