Certainly better than a "welfare society" where everyone is just a cog in the machine completely dependent on government assistance.Welcome to "The Ownership Society".
Anyway, back to the point about how long it will take to turn over the current generation of cars, I think it is already getting close to the point where it is economically rational to park the gas car and buy electric, especially if you just commute through an urban environment. Cheap NEVs are already available, and you can pay one off in as short as 3 years with the savings you get from not buying gas. Gas cars are a money sinkhole. Not only because of the price of gas but because of all the maintenance.
