So basically something like personal rapid transit, first deployed ~50 years ago? And for which virtually every implementation has disappointed?

It's called "transit signal priority", and has been around for at least 20 years.
- triceratops 3y agoIt's disappointed in the past partly because it's slow and expensive because you have to pay human drivers. And because there's a human driver, you have to have at least a 4-seater vehicle and that increases fuel and maintenance costs. Signal priority is only at signals. I'm talking about private cars changing lanes to let public transit pass through. Human drivers will only do it for emergency vehicles, but you can make it a condition of licensing for a private driverless vehicle.
