The traffic today was terrible! The city of Lancaster with the population of 35,000 people had more traffic on that time than my city in Brazil, Jundiai, with 350,000... Probably because the average is 37 cars and a half per family and it has no public transportation. And there's no one-way streets.
One-way streets make a little confusing for foreigners because it is different, but it makes the traffic flow so much better. You can have 24/7 synchronized lights so you will get only one red light per street you are going. And street signs here in the U.S. is a little messed up. Too much confusing stuff, confusing signs and some of the intersections has lights with 12 different combinations of left turn only, then straight, then straight and left turns, then only west, only north, it's like Frankenmuth on Christmas' eve.
