Why not? It probably goes back to the OEMs, and part of the challenge is infrastructure.
People are comfortable with gasoline. We have a culture that's comfortable with it. We have auto manufacturers who know it. We have a sophisticated distribution system. We have gas stations on pretty much every corner across the country, and that's okay, but getting Canadians to think differently takes time, money, investment, and maturity of the industry. It's not just the individual.
When it comes to propane, the technology has matured over the last 30 years. We had an issue about 25 years ago with conversion. There were incentives offered, and it seemed like anybody with a ranch was doing the conversion, but they were doing it wrong. When you have one chance to get it right and things get done wrong, it tends to stain you for some time.
If we get some more OEMs to produce propane-powered vehicles, it will allow us to put more infrastructure in place to make it easier. Eventually we could go the way Europe has. At one time, they were filling up their BMWs in the middle of the night with propane, but they don't have to do that anymore. They can go to any filling station during the day and self-fill.
It isn't just one thing; there are a lot of stars that have to line up, including the regulations and standards across the country. It is these standards that would allow us to do what is already being done elsewhere in the world.
That's a complicated answer to a simple question.
