100% agreed, which is why I never thought that AV's were the cure-all for our cities. I was always concerned AVs would induce urban sprawl, for instance, by allowing longer commutes to become both cheaper and more tolerable.I have a couple more thoughts on this. Tony Seba is predicting that with the speed of AI advancement, autonomous cars will have all the kinks worked out and be ubiquitous by 2030, and that transportation as a service will be 10x cheaper than owning a car. He's also predicting that because of this, the vehicle fleet will fall by 70% and the remaining cars will be continuously driving. And that the cost savings and increased productivity will be a tremendous boost to the economy, and that the need for parking lots will be drastically reduced.
This has a few implications that he hasn't addressed. First, rush hour will still be a thing. For all the hype of telecommuting, face to face contact is incredibly important in most sectors and the vast majority of us need to get to a physical workplace. So the minimum number of cars we'll need is how many are required to deal with rush hour. At non-peak periods and especially at night, a lot of cars are just going to be sitting somewhere, so we might need more parking lots than Seba thinks.
Second, if car transport is going to be the same annual cost as a Netflix membership, it makes car transportation essentially free. And since reducing the cost of something, drives up demand, people are going to take trips more often and farther than they do today, and that means more cars and more traffic.
I'm still bullish on the future being electric, automated and on demand, but I do think that it'll be more complicated than Seba thinks.
Though there are some important changes as it relates to the public realm. Parking lots can be located at areas in the urban periphery, rather than downtown, to store vehicles at non-peak hours. Storefronts and buildings can re-utilize or redevelop their on-site parking to more productive uses. We can eliminate on-street parking and increase sidewalk width, add cycling lanes to most major streets. I am sure there are more public realm changes that could be enabled by AVs.
