But you don't need to buy a new bike for every senior every year. Bikes last. In steady state, you only need to buy one for whoever retires that year, which is maybe 3 million per year. So the cost is roughly $45 billion per year, and that's assuming all retirees participate.
As for cost, I expect mass production on a vast scale would ultimately drive the price down. Every damn vehicle manufacturer is going to want a piece of the GLR* contract. They'll knife each other in the streets for it. $10K per unit seems like a workable target.
[*] Let me just say, in my official capacity, that the initials do not stand for Granny's Last Ride. They stand for, uh, something else.
