So, if a traffic light never changed from red to green, you would advise..? Or do you just mean “in that situation, be very careful not to crash”?

Call the cops and have them organize traffic, they have a literal traffic department.

This is the problem with leaky analogies. The US immigration system is more like a train tunnel in a Wile-E Coyote cartoon that Roadrunner can run through but Wile-E slams into.
