Uber is not the answer really as is, but some form of fewer cars used more often with much less parking needed — that would be an improvement.
If we can then get rid of half the parking lots and fill them in with a mix of medium-density mixed-use development and green space, that could set us up for enough walking/biking/transit contexts that we can take the next step away from car dependency.
It would be some bit of legal/liability wrangling and maybe some accounting to do it, but imagine if you had 50 families in a building, and ten vehicles available ranging from a small car to a pickup truck to a van to a moving truck. Tune it a bit and there you go!
