It shouldn’t be allowed on a public street!
You critics are making a lot of assumptions. I read about this vehicle a few months ago while car shopping. It has a decent structural cage designed to protect the passengers. IIRC, it gets closer to 60 MPG, not 40. Yes, a vehicle that weighs 3 times as much is safer. However, we should just let the consumer decide whether gas mileage or extra safety is more important. BTW, I bought a Toyota pickup that gets twice the mileage that my Ford got before. There’s nothing wrong with conservation. At least I send only half as much money to the OPECKERS as I used to.
