Well, one of the long-term benefits is that it would be a great alternative form of travel for an aging population. It may not be a big deal for most of us young folks to make a two-hour drive non-stop from Calgary to Edmonton, but for a couple in their 70s, it's more likely to take 3 hours plus bathroom breaks and a lunch break. I hate to perpetuate stereotypes here, but an aging population doesn't make for safer driving conditions, especially on day-long trips. Personally, I'd be much happier knowing that certain relations of mine were taking the high-speed between Calgary and Edmonton, rather than making that long drive every few weeks.
