Everybody's focused on "sharing" -- is it actually the right first path?
I wrote earlier about Cruise's "Origin" which they say is a vehicle devoted to shared rides. Many other companies also are hoping to make vehicles for shared rides -- it's treated as almost a received wisdom. But the reality is that sharing rides isn't all that it's cracked up to be, and to work what you really need is frictionless instant mode transfers so nobody goes out of their way. And for that you need automated single person pods, not big shared vehicles. In fact, the cost of a human driver, per passenger, isn't that bad on shared riding -- it's in the last mile that the cost is too high.
