Earlier quoted context omitted.
You have the deal with the bike afterwords. Go for brunch in the mission and your friends are going back to the outer sunset with a scooter just fold it up and put it in the car with a bike either hope it's there when you get back, bike all the way, or go home then head over alone.
This exactly: bikes require planning and strategy and are not good for improvisational day-to-day things like you described. Bikes make walking easier but all other forms of travel like bus, train or taxi/uber/cars more difficult or impossible.
What? I don't plan or strategize any more or less than someone getting in a car might think about the optimal rush hour route.
