Sometimes a picture is worth a thousand words. A GIF is worth even more.
The animated comparison of a streetcar vs. cars on a Toronto street is all over the Internet after being posted by The Atlantic. But the pictures themselves come from the Toronto Transit Commission, which posted them to Facebook way back in 2009. Tumblr user Peter From Texas appears to have stitched them together to make the compelling GIF.
Many Torontonians will be quick to point out that the streetcars are hard to pass and have a nasty habit of leaving traffic jams in their wake. Then again, if everyone took transit that wouldn't be a problem.
