It seems to me that there is a lot to learn from Europe's experience with Diesel cars, not the least of it being that the future has a way of differing from our expectations and that even when we are fairly confident of our opinions, we will sometimes be wrong in a way that turns out to be significant. I found the following article Europe's love affair with diesel cars has been a disaster - Vox here Vox.com - Europe's love affair with diesel cars has been a disaster - TDIClub Forums. I found the content informative, thought provoking and pretty balanced with lessons that extend beyond diesels.
