I've always wondered why Ontario highways have such extravagant exits in rural areas. Even if there's maybe 10 cars a minute on the highway and 2 cars an hour on the exit road, they have a huge half-clover intersection with enormous acceleration and deceleration lanes. Acceleration I can accept, but why such a long deceleration lane? And why the two clovers?

^The parclo is the standard MTO interchange and it's caught on around the world. It's future-proof as it can handle high traffic levels and eliminate left turns onto the freeway, unlike a diamond. On a couple highways if there's not enough traffic for a full interchange they've just built intersections with the intention of building full size interchanges in the future. Hwy 11 towards North Bay is like that.
