Since we're talking about road space, check out the 20 lane highway in Burma. It has a lot of soaking up to do.

It was on an episode of Top Gear. It's typically empty, and in the above image you have government officials going to work.

I'll see your 20 lanes and raise you the Katy Freeway I-10 West in Houston. http://imgur.com/gallery/TYfGrIY

I drive this god forsaken freeway just about every day. Average top speed during commuter hours is about 10-15 Mph in both directions.
