Therein lies the challenge. From an execution point of view, it's not been done so far very well.
There remains the challenge with light-duty vehicles that when you add up the number of options for a gasoline vehicle consumer in Canada, you start to run out of fingers and toes very quickly. The challenge for light-duty vehicles is that consumers are fickle. They have a whole range of needs, whether it's a pickup truck, a station wagon, or a sports car, and it becomes very challenging to think of the investment that's required to get to that number of choices.
I think home refuelling, though, is a very good option if executed technically well.
