Coco, 7, stares from behind glass out of the window of a car driven by Baton Rouge's Mergie Barbier, 'in-car-cerated' in heavy holiday season mid-afternoon traffic on Perkins Road near Essen Lane, Tuesday, Dec. 19, 2017. The dog, owned by Barbier's cousin Lettie Moroney, also of Baton Rouge, could only look at the outside world, as the car was in a line that took several cycles of the stoplight to pass through the intersection.

The holiday promise of peace on earth and good will toward men can seem elusive on south Louisiana roadways this season, as Yuletide shoppers stress an already strained traffic grid.

The bustle is a happy sign of commerce, a particularly welcome development since local governments depend so heavily on sales tax revenues to fund basic services. With the national economy surging, Louisiana’s holiday shopping season could be an especially strong one, and we certainly hope that’s the case, since many local merchants depend on Christmas sales to stay in business.

Those crowded streets demand our patience, though — and extra care in safely navigating the congestion. Bumper-to-bumper traffic can give all of us a case of the bah-humbugs. Here’s hoping that Christmas cheer, not Christmas jeers, will win the day.
