To be honest with you, because of the hyper-competitive nature of the trucking industry, it has to be a certainty. You don't compete based on your equipment; you compete on other factors. Therefore, your equipment has to be certain.
If you leave from Toronto to go to L.A., you need to know that you're going to be able to fuel that run with complete certainty and that you're going to be able to maintain that vehicle with complete certainty. Until those certainties are on board with other fuels or other technologies, which we do not have currently, that's not going to happen.
