"Being able to rely on buses as a piece of infrastructure" is the reason. Because you don't want to buy a car for two parties a year that run late. Just as you wouldn't want a disused sidewalk or a country road or a bridge to close completely during periods when they're not being worked to capacity. This isn't a major advantage of buses, it's a major cost: They're so expensive to run that you only get to deploy them for peak periods. If you _do_ have to buy a car for two parties a year that run late, well then why not use the car for the daily commute? If everyone made that choice, it would destroy the city. The availability of Uber et al is a massive public good for a city, because it can patch over failures like this in our public transportation system in a demand-responsive way without inducing a lot of additional traffic.
