    Perhaps so, perhaps not.

    And then there is the question "which rails"?

    When our downtown bus tunnels were built, rails were installed in them
    so that they could be used if and when the voters approved a light
    rail system.

    And they /did/ approve it; I even rode it a year ago January. But the
    people building it found that the rails installed were the wrong type
    for the trains they were planning on using.

    So the old rails were torn out and new ones put in.

    But, hey, we did eventually get rid of the Off-Ramps to Nowhere <https://arboretumfoundation.org/2024/04/18/ramps-to-nowhere-removed/>.
    It took decades, but even the one I most remember because I saw it so
    often (a very tall single-lane which connected to nothing at both
    ends) was removed eventually. So it isn't as if building something and
    then removing it is anything new around here.

    and replanned
    due to increases in traffic.
    In San Francisco when I was much younger and before I came to live

    There are a lot of communities (mostly suburban, AFAIK) that are so

    Seattle is trying to move from car-centric to something-else-centric,
    but resistance is strong and alternatives are weak.

    The Netherlands, in the 1970s, made a deliberate pivot away from cars
    and to public transport and bicycles in the 1970s.

    Well on the lower level it was truck traffic to and from San Francisco
    and 2 sets of rails along side the the Trucks. The rao; cars were
    smaller than
    you might expect since they were designed before WW II and did not usually enjoy much ridership from what I saw.
    The first time I came to San Francisco was to bury my father in
    the Presideo Cemetary in 1939 and we traveled from Redding, California
    to San Francisco by train and by Ferry. I was 2 and 1/3 years old.
    All I remember is the flag being handed to me and that it was a cold
    day on the hillside were my father was buried. Those are common
    conditions at that location. I was asleep most of the trip back and
    forth but I remember that train.

    Realize that Bobbie is speaking of the 1950s. The last train across the bay was
    in 1958. This was near the start of the post-war age of the automobile
    in the USA, and rail was considered obsolete (yes, that's foolish

    (https://en.wikipedia.org/wiki/General_Motors_streetcar_conspiracy)

    The bay area in general has seen many of the historic rail right-of-ways
    fall to housing development. There is very little freight rail traffic
    in the entire bay area (aside from the Oakland port freight traffic
    headed eastbound across the sierra and cars from the fremont tesla
    plant heading east).

    The Santa Cruz line along the coast, for example, has fallen into signficant disrepair
    and efforts to reanimate it for passenger rail are failing due to the cost of replacing
    many dozen small viaducts and wooden bridges that are over a century old in some cases.

    Earlier on there was a rail line at the western waterfront in San Francisco.
    You could see fragments of it from the walkable part of the old road that
    was taken out in a quake. This is over behind the VA Hospital and the
    Museum
    behind the municipal golf course. That road was part of a Scenic Drive.
    That rail line was built too close to the surf and its footings were washed
    away by storm waves.

    In MA, I've been getting free ride with my EV so far. It is not
    fair, and I'd have no qualms about paying a reasonable level of tax,
    based on annual mileage, scaled to the average tax paid by a
    similar ICE car.

    Currently, most states charge a fixed annual fees.

    https://costtocharge.com/guides/ev-registration-fees-by-state

    These vary from 0 (my case) to $270 (New Jersey, and you have to
    pay 4 years up front on a new EV!). At 49.1c/gal tax in NJ, that's
    about 550 gallon's worth of tax. At 40 mph, its the tax you'd pay to
    drive 22,000 miles.

    Seeing as the average miles driven is around 13,600, the NJ
    registration fee is about 50% high to be fair.

    This was a five star read for me in February 2014 and I have begun
    rereading it and am loving it. I am surprised both with what I have
    forgotten and what I remember. The group minds of the Tines are just fascinating. There is a 2002 version of this book which includes all
    Vernor Vinge's notes whilst writing; notes about all sorts of things
    from word choices to character consistency to plot. These are
    interspersed throughout the book and there is also an introduction by
    Vernor Vinge about them. This is a bit woffly but enough to search for
    and I think that you would appreciate it.
