They've also set trucks that can reliably drive around private roads, mines and loading zones without having to handle much in the way of novelty or people as a practical near term goal they'll probably make a commercial success of even if fully autonomous cars are decades away or incapable of ever being viable for regular unsupervised road use.

Obviously it helps that they're already a leading truck manufacturer, but it's interesting to note how many other ventures have gone for the "eliminate the taxi sector and reinvent car ownership" over the low hanging fruit for [semi]-autonomous vehicle markets.
