We have much to be thankful for this Thanksgiving Weekend. If nothing else, be thankful that you weren’t stuck in this 50-lane traffic jam on China’s G4 Beijing-Hong Kong-Macau Expressway.  The culprit: a new checkpoint that forces traffic to merge from 50 lanes down to just 20. This is more than a nightmare – it’s carmageddon!
