The winter driving range controversy could be addressed with a simple questionnaire for any prospective buyer:
In what state do you live?
Select the model, wheel configuration and type of tires.
Estimate your typical highway speed: 55, 60, 65, 70, 75, 80, 85
Will you use the cabin climate control in winter, yes or no (will only use the seat heaters)?
It should be easy to estimate the Wh/mile, the estimate the driving range. The buyer should sign off that they understand, accept the estimated driving range before purchase.
