World's Worst Commutes Beijing and Mexico City lead the way By John Johnson, Newser Staff Posted Jul 2, 2010 11:31 AM CDT 7 comments Comments Rush hour in Los Angeles. (AP Photo/Reed Saxon) (Newser) – IBM surveyed drivers in 20 of the world's biggest cities to find the worst commutes. The bottom 5 (based on a slew of factors including time stuck in traffic and stress) in the commuter pain index are: Beijing (99 on a scale of 100) Mexico City (99) Johannesburg (97) Moscow (84, with 2½-hour traffic jams common) New Delhi (81) As for US cities, Los Angeles (with a score of 25) came in at No. 14, New York (19) at No. 17, and Houston (17) at No. 18. Most American drivers say things are getting worse, though 8 in 10 drive to work solo, notes Wired. This matters, writes Richard Florida in the Atlantic, because "every minute shaved off America's commuting time is worth an estimated $19.5 billion."
