Buses should go all the way into destinations such as Barton Springs, shopping malls, and parks, not drop passengers a quarter mile or more away, sometimes across busy streets. A quarter mile on a busy street can be a long trek for a pedestrian, particularly a disabled pedestrian or a parent with small children. Our current practice of keeping children in their parents' cars until they are old enough to drive cars themselves is extremely counterproductive. Remember that the goal of a public transportation system is to enable people to move around freely without cars and even without bicycles. Don't design a system that won't work without cars.
Cars are expensive, both monetarily and in other ways, for our whole society.
Don't let cars park in bicycle lanes or on sidewalks. If a household has three cars, some of the house's yard should be used for parking the cars, not public street and sidewalk space. Sidewalks should be acknowledged as public space, and maintained by the city. Advertise the airport bus and put it in the same part of the airport as other ground transportation. The airport bus needs to run at least until midnight, especially is the City Council continues to meet there.
