Chicago drivers have been adjusting to a new reality since the Nov. 4 election: Wherever President-elect Barack Obama goes, traffic disruptions follow.
Traffic tie-ups also precede his high-security escort from his home in Kenwood to federal offices in the Loop and anywhere else the soon-to-be commander-in-chief may travel, even to nosh on a corned beef sandwich at a deli.
Some drivers are quicker than others when it comes to learning that the absolute worst time for a motorist to appear impatient, menacing, curious or even plain stupid is when the presidential motorcade is passing by.
A few incidents have occurred in which Chicago drivers failed to yield properly to Obama's heavily armed caravan of Secret Service and Chicago police black SUVs and other vehicles ablaze in flashing lights.
It can lead to trouble. And offenders should not count on receiving a presidential pardon.
