Have you noticed the number of Toyota Prius around town? Or is it the same one I am seeing multiple times? I honestly do not feel there are that many committed ‘green’ drivers out there.
Camry Hybrids are also fairly common, so perhaps I am letting my personal bias get in the way. With the price of petrol in this country still being very much cheaper than the UK for example, why would you bother? Petrol is still the cheapest thing you put in a motor car.
