> Transit uses an implied hub and spoke network system where the base level of spoke is walking, then some combination of buses/trains/subways integrating those walk-sheds.
Not necessarily. Minibuses, bikes, e-scooters, even cars (park and ride, a big parking next to a train station; you get off the train and on your car for the last/first part of your trip) are perfectly viable "last mile" options.
I prefer not to get killed in a traffic crash. Even personal mobility requires infrastructure like fully separated bike lanes and multi-use trails. A white paint line or sharrows is a joke.
We have level of service standards for roads and highways. But for pedestrians and bicyclists there's no standards for sidewalks on every street, bus stop quality, tree canopy, protection from speeding SUV drivers, crosswalks, bike racks, etc.
