The forecasts of the speed of EV adoption vary widely. I was pretty surprised by the differences. The US Energy Information Agency predicts about a 5% adoption by 2050 Meanwhile, Energy Innovations forecast over 20% Bloomberg New Energy Finance by 2030 and nearly 70% by 2015. A lot depends on the speed technology lowers costs (particularly batteries), gas prices, and regulation. This is EV, not AV, but it seems you need EV for AV.

Since I last checked in, Ford announced it was likely dropping IC sedans and increasing investments in SUVs, tucks, and trying to catch up in AV. AV is where the investment is heading.
