Depends on where you're at. My girlfriend's car is currently awaiting a new engine at the dealership. It'd take about 30 years to build up the infrastructure in my city (a major one in the Lower Midwest) to get to where it would need to be for her to not need anything other than public transit, and that's assuming nothing else changes (like even further urban sprawl) and that we had the political will to start today - we don't. Maybe in Europe, Asia, and a select few North American cities it'll be dead, but there will still be plenty of places where it's necessary.
