Canada appears to have some terrible problems with hills, and a road budget that doesn't lend itself to cuttings through them. The trucks drive far too fast and I could swear that at one point, one actually took all wheels off the ground as it crested.
The photographer also drives too fast: speeding off the highway onto a track, the vehicle ended up inches from the dunes! Efficient brakes, though. I quite enjoyed some of the spectacular four-wheel drifting.
