I'd think that the social isolation feature has benefits whenever communicable diseases are in the air, which seems to be every winter. The autonomous nature of the system means each CAR can change from road to road to route around congestion and construction, in a way that mass transit can't. And of course, the time saved by being able to go from point to point rather than through mass transit hubs quickly adds up to many lifetimes. I agree that pollution is something that needs to be addressed, which is why electric and hybrid CARs are being introduced by startups and legacy players in the industry.

If your transport system is good enough this isn't a problem either. In London, you're rarely more than 5-10 minutes from a tube station. And they'll likely be buses even closer. Public transport is much quicker than driving for most journeys. I think I know fewer than 5 people who own a car here.

  Finding a route without congestion is literally impossible for trains stuck on a dedicated track. One little traffic problem shuts down the whole line, including all stations along the route. Since lines are typically connected without redundancy, a failure can partition the network into two disconnected halves. All it takes, in one tiny little spot anywhere on the line: derailment, flood, suicide, stuck switch, malfunctioning sensor, failed motor, wrong kind of leaves on the rails, wrong kind of snow on the rails, broken signal, street-running car crash, tracks blocked off for a crime scene investigation, bomb threat...

    Well sure, but in practice on a well-run line this doesn't happen very often. Especially on underground lines which don't have weather realted problems. This maybe happens to me a couple of times a year. Whereas roads often have traffic jams every day.

> I'd think that the social isolation feature has benefits whenever communicable diseases are in the air, which seems to be every winter. Probably true, there's an advantage there. But there's also an advantage in walking + transit, in that it helps people stay healthier. Between the car-dominant US vs the more transit-friendly countries of Japan, Korea, and western Europe, one side has a health and lifespan advantage. And it ain't the US. > The autonomous nature of the system means each CAR can change from road to road to route around congestion and construction, in a way that mass transit can't. And yet, commute times in the US are basically average compared to other developed countries. Would you care to explain that? > And of course, the time saved by being able to go from point to point rather than through mass transit hubs quickly adds up to many lifetimes. Source on transportation time actually being lower in car-dominant areas?

Of course, the lack of exercise which tends to be enabled/encouraged by using a CAR kills a lot more people than infectious diseases do. > And of course, the time saved by being able to go from point to point rather than through mass transit hubs quickly adds up to many lifetimes I suppose this depends on where you are, really. This may very well not be the case in a large city with segregated rail/light rail/bus. Also, of course, you'd have to find a place to leave your CAR; no small feat in a large city.
