> Cars are the slowest, lowest-bandwidth forms of urban transportation. This is the kind of thing I read a lot in micromobility advocacy articles, but it seems like it can't be true. How can a bike, scooter, or moped be either faster or higher-bandwidth than a car? Also, serious question: if electric SDCs became widespread, would it still make sense to advocate things like bikes? You can't transport a family of three…

Yes, absolutely yes. The cars would still have to go somewhere after they have dropped off their occupants. Hopefully we will get on-demand carpool services that allow us to have vastly fewer vehicles on the road, which would free up space for bikes and other public transit.
> You can't transport a family of three or a baby as safely in a vehicle smaller than a car
Not everyone can use a bike of course. Some will have to use public transit, and yes some will have to use a car for various reasons. The streets don't have to be car-less, we just need to get enough cars off the road to ease congestion and be able to turn existing lanes into bike lanes or public transit lanes. Once good reliable and quick public transit exists, there won't be such a strong incentive to own a car.
