Approaching Toronto on a typical Friday evening, Highway 401, the major artery connecting the Windsor-Detroit border with Canada’s largest city, is more often than not jammed. Pick-up trucks pulling campers or towing snowmobiles, SUVs crammed with tents or skis, and bumper-to-bumper tractor-trailers in the slowest lane of the world’s widest highway resembling a train. It’s enough to make an environmentalist weep.
