They periodically catch my eye. There are a few companies from India that are doing some amazing things. One company has a car that uses compressed air, and has a backup diesel compressor built in. Even if you air exclusively on the compressor the mileage is still crazy. There is another company also from India that builds extremely inexpensive, very tiny cars, that use very little fuel. They have recently started selling cars in the U.K.. The issue most people have with owning and driving a high economy car is most have very little get up and go. In Canada and the US we do a lot of open road and highway driving, where as there are a lot of places where driving is mostly done in very high congestion areas do not have the ability to go fast and for those places the high efficiency cars are very sensible. I cannot imagine trying to drive one of the high effiency cars on a cross country trip, and certainly not with my driving habits. There have been some nice diesel cars come out in recent years that are a nice medium for where I drive cars. At home a pick up is most sensible. I am intrigued though, very intrigued.
