See the November/December 2019 issue of Automotive Engineering from SAE. There are articles on driving a Jaguar I-Pace round trip from Pittsburgh to Detroit. There is an article on solid state battery development. We have a number of Amish and other sects in several states that practice a low tech life style as part of their religious beliefs. They are well regarded here for their construction skills. There is a variety of practices from group to group on what technology is acceptable. A race car builder in Pennsylvania produces high strength buggies to spec that are crash resistant. The buggy builder near me uses Timken roller bearings in the wheels. As one farmer replied, "You'd be surprised how well you can live if you don't buy a new 4 wd truck every year."
