Why wait somewhere between 3 to 50 years for this technology to be ready?

Transit can do this for us now. Fund it. Give it priority on our streets. 

Plus, driverless cars are still cars. They still take up the same amount of space, still use the same amount of energy, still pollute just as much, still require massive infrastructure costs to operate them. There are a lot of problems with cars that automation does not solve, but transit does.
