Some Confusion and Major Omissions

First, at present Uber only buys cars from OEMs; Volvo in Pittsburg. So including Uber here with researchers and manufacturers is, to be generous, confusing and misleading. If this were to be your metric then Didi in China would be a bigger player (and, yes, Uber is an investor). Also, included would be Lyft and European companies, at a minimum.

Second, and more important are all the other companies from Europe, Japan, Korea and China not included. Nor is Faraday in the U.S.

Finally, you excluded trucks, which are likely to be first big roadway application, and companies providing add-on kits to modify existing vehicles, which is trickier.

Nice graphics, curious rating system, bad analysis.
