The worst of them is the stretch of I-405 north that runs between Exit 43 and Exit 21. Widespread traffic bottlenecks have the potential to cost L.A. drivers a staggering $91 billion in time wasted sitting in traffic by 2026 unless the situation somehow improves. By definition, a traffic hot spot is one in which observed speeds drop below 65% of the road’s otherwise uncongested speed for at least two minutes. NYC’s worst traffic crawl occurs on the Brooklyn Queens Expressway east between Exit 28A and W Shore Expressway, where it takes the average driver 64 minutes to cover just 4.4 miles. Say what you will about the joys of motoring, but for those who suffer the worst traffic bottlenecks on a daily basis, the self-driving cars of tomorrow can’t come quickly enough.
