Here on the south end of Vancouver Island those little SmartCars are everywhere! 3-cylinder turbo diesels that get 70+ mpg. There is a waiting list to buy one and the City of Victoria is implementing reduced parking fees for vehicles less than 1.6 metres in length. Excellent! They are looking at reconfiguring some parking lots to accomodate a larger number of smaller vehicles.
I also own a diesel vehicle.
Unfortunately, it weighs almost 2 tonnes, and is guzzling diesel through a 6.5litre V-8 turbo. There was a time I needed such payload capacity but I'm done with that, and I missed this behmoth's "sell-by date".
It won't run properly on the corn oils or biodiesel, either. The emissions sensor clangs on something it doesn't like and throws a warning light on my dashboard and by-passes the turbo.
Then, I have the luxury of sucking down biodiesel with much less efficiency.
I've been going grocery shopping on my motorcycle recently. Can't buy the Econo-sized stuff that way, but it's good for fresh produce and other immediate consumables.
Anyone need a big dually 4x4? With enough rope it can pull a small planet out of orbit.
