Could I get in one quick last question?
I was reading an article the other day about the flexibility of fuels that you can have in different parts of the world. They were noting in China it's methanol and gasoline, back and forth, and Brazilians have a bunch of options, including ethanol and natural gas.
Are there specific challenges in Canada that would make it difficult for us to adopt more ability to flex between different fuels? I'm not just talking about ethanol; it's a whole range of things. What specifically in Canada would stop us from taking on those innovations such that people could then shop in a marketplace between options of fuels for their vehicles?
