Very true, but retrofitting good transit into a city that didn't plan for it is extremely expensive and disruptive. I see these kinds of services being a great complement to public transit in cities that have struggled to make them attractive.

For example, I am way more likely to take Cal Train into SF if I can use a point-to-point service like Uber/Lyft/Waymo to get me the rest of the way there. Without that missing link, I'm much more likely to just give up and drive instead.
