  • And walkability.

    When I first moved to Boston many years ago, I had some enlightening experiences. I loved how walkable Boston is, I loved trains, but I did not expect the the feeling of freedom I got from leaving my door with only a T pass in my wallet and Having so much of the city so convenient.

    It was revelatory just how much more convenient that was than using a car, when all my life I expected to use a car to go practically anywhere. The challenge is sharing this experience among others who have only known car life, making the advantages real, immediately beneficial.


  • Everyone thinks the sky is big, without considering just how unscalable flying cars are

    • no building is designed for large scale entry/exit at roof top. Most don’t support any
    • the low altitude airspace over a densely populated area is very limited. Given current separation, minimum altitude, speed limitations, a city can support only a small number of flying cars. And no, “smart” vehicles don’t change the laws of physics, even if they help us get closer to them
    • a flying car will always be more expensive than a not flying car, which will always be more expensive than transit

    Let’s stop worrying about new ways for the ultra-rich to avoid the frustrations the rest of us have to deal with, we’ll all be better off if they also have an incentive to design more effective cities and transportation for everyone


  • And yet a coordinated approach with multiple strategies will most effectively cover every use case.

    • conservatives get too attached to personal vehicles as the strategy they are most familiar with, most focussed on
    • too many transit advocates recognize the limitations of personal vehicles and the advantages of rail, but tend to speak in absolutes that scare conservatives.

    Yes it’s critical that we refocus much of our transportation effort to give more people better choices in more scenarios, but that will never rule out cars
