He talks about the tyranny of parking lots, but this is a solved problem! The whole presentation is an exercise in steadfastly not talking about public transportation.
He actually did address public transportation, saying that fully autonomous, on demand taxis will be the equivalent of individualized public transportation. He's right. Why would I want to stand outside in the elements for 20 minutes waiting for a bus when I could hail an autonomous taxi and be on my way?
"Just ride a bus" is the "640K ought to be enough for anybody" of the current cycle.
A bus can transport 100+ people while taking up about the same road space as two or maybe three of these. Those could transport 4 or maybe 6 people. I don't think more needs to be said about the chances of this replacing actual public transport.
One problem is regular trips, such as commuting and shopping, where most people need to regularly go from residential areas to office areas or to commercial areas. Here, the vast majority of people, all over the world and with few local exceptions, use public transport (trains, subways, trams, buses, etc). The fact that you have to walk a little bit to the station and from the station to your destination is not a major concern, compared to the cost and the time difference VS filled city streets. If all the people commuting, say, by subway in Tokyo were each in a robotaxi, you'd need most of the day just to finish the morning commute.
Then there are more independent trips, where your schedule is not aligned with public transport, or where there is some urgency, or where your destination is very far away from a station, or where you have very heavy bags etc. For those cases, a car is of course the ideal, so lots of people, even many of those that commute daily by public transport in cities, also own a car.
The bus can only transport 100 people because it forces everyone to take the same route, regardless of where they are actually headed. This is not merely inconvenient, but a delusional take on the future of mobility.
You cannot eat on the bus. You cannot bring your grocery bags on the bus. You cannot bring your pets on the bus.
Also, there’s the fact you have to sit with (and smell) 99 other people. Some of them you may find are mentally unstable shitbags that will possibly assault you.
Sure, there are inconveniences, but it is literally impossible to run a huge city any other way (I mean, other than fixed route large vehicle cramped public transport, be it busses, trains, trams etc). It is geometrically impossible to fit 20 million people on roads in cars during 1-3 hours when businesses start and end. Drivers make no difference, the problem is the form factor. This is not a technological problem, not even a physical problem, it's a problem of basic math.
Does he not understand the point of public transportation or is he hoping the people he says this to don't understand the point of public transportation?
