Not just any traffic jam. It will be all the sinners of eternity lined up for millions of miles on a causeway behind two people trying to turn left and blocked by traffic from the other direction, with no one willing to get out of their cars and strategize to have someone pull off onto the side street to let the left turner through since they wouldn't benefit in their direction, and neither left-turner willing to change their travel plans.
@AlphaCentauri I almost spit soda through my nose when I read this. You even had an awesome visual. Well played!!
