Lets talk about electric vehicles and self cars like Tesla and others.
There are several great Youtube sites to check out to learn more about affordable electric cars like the $1,000 ones coming from China now.
This site Donut Media is an excellent source of information which is served up in a very humourous way. https://www.youtube.com/watch?v=c0gqZS18nfw
This site Jalopnik on Youtube has several videos which discusse the many benefits and some drawbacks of the $1,000 China electric car. It has what seems like the equivelant of a washing machine motor and many ways to cut costs like having only back brakes since the vehicle is so light and using old school lead acid batteries instead of the more costly lithium ones. https://www.youtube.com/watch?v=1GG1RC7GV0Y
