To be fair to Leno, is he pushing for everyone to drive these types of cars or is he just genuinely pushing this type of challenge?Don't know, don't watch him and don't care. As long as he has that stable of cars & Harleys, he should STFU on 'green anything'.
The climate control (HVAC) required just for his 'garage' is enough for a cul-de-sac of houses (about 20).
