The thing I am surprised by is that we don't purchase diesel passenger cars and trucks

Diesels have a bad name in the Northern states. In Wisconsin, some cold winter nights easily dip into negative fahrenheit (or about -20 celsius), and diesels are notoriously hard to start in that kind of weather. You're increasingly seeing Mercedes and others produce diesel cars - like they used to on a more frequent basis 20 or so years ago - but it's a hard sell to move those cars in our area.

The modern diesels start easily even at -40F. I own one and I live in Wisconsin.
