Thanks for the data.

More number crunching is required however. See, we stopped producing all gasoline vehicles today, based on your source, it would take 11.4 years in average for the fleet to be replaced, so it would be an obvious win.

But we are not doing that. As this whole EV vehicle discussion proves, it is very difficult to replace the fleet. And the infrastructure.
