"Point to point" is a huge part of the appeal of cars over the existing public transportation network. We dedicate a ton of space to enabling point to point for cars, and barely any for bike docks and the like.

Dockless scooters are the most effective thing I've seen yet - in very limited areas, so far - at starting to combat the limitations of the public transit network compared to the road/sidewalk/parking lot network. Bikes are too big to work well in this way, but scooters have done well.
