I wonder why there aren't more EV trailers on the road, a trucking company would be more willing to absorb the higher initial costs of an electric truck in order to save on fuel down the line. Is it because EV can't effectively compete in terms of fuel costs against to long range you get with diesel. Or is it just short sightedness among manufacturers EDIT: actually looks like I spoke too soon: https://nikolamotor.com/one https://nikolamotor.com/one https://www.forbes.com/sites/alanohnsman/2017/04/13/if-you-think-the-world-needs-tesla-semis-and-pickups-elon-musk-has-good-news/#1d5f7fc96491 https://www.forbes.com/sites/alanohnsman/2017/04/13/if-you-t... https://www.forbes.com/sites/alanohnsman/2017/04/19/toyota-rolls-out-hydrogen-semi-ahead-of-teslas-electric-truck/#22ce9c1e582b https://www.forbes.com/sites/alanohnsman/2017/04/19/toyota-r...
