It's absurd to think that transit buses containing dozens of riders are going to be held up behind zero-occupancy vehicles. The roads are going to get much much worse.
Source? Buses actually work very well in many places (and are much more economical and efficient than cars). The simplest way to make buses work well is to give them their own lanes; there's no reason a vehicle holding dozens of people should be held up behind single-occupancy vehicles.
Buses are the best blend of resource efficiency and cost efficiency in transportation, full stop. And that's today, no additional inventions necessary.
So, at 6pm a thousand people call up the efficient fast driverless cars to go home....
And that's just one office out of a dozen on that street.
- somehow find other people "with similar destinations"
- somehow synchronise the time they leave work
- figure out who calls and pays for the robo-taxi
How is that effecient?
And, once again, that's just one office on a street of a dozen or so office buildings. Across is a building that houses 10 or so different companies. So I guess those people should also somehow group themselves across companies?
