'cause if heavily regulated cities are known for anything it's no traffic problems and well protected communities.
A lack of zoning and forward planning makes traffic worse. Take for example, Woodruff Road in Greenville, SC. Rather than planning out the commercial zones of the city, no care was given to were businesses could go. Almost all major retailers built onto the one road and it is now known as one of the most congested roads in the city. Now it's too late to make major changes. While highly regulated cities can have traffic it is generally made worse by uncontrolled sprawl.
