I propose a new carol

[highlyeccentric]

In the true spirit of the Christmas-New Year Period:

Pack the roads with cars and trailers (fa lalalala lalalala):
Drive the locals mad and bonkers (fa lalalala lalalala)!
Barely moving, on the freeway (fa lalalala lalalala)-
Jam the bypass, and the highway (fa lalalala lalalala)

There's more verses to be written, but I haven't managed to come up with them yet
