Christmas is a religious festival to many - most major religions have some sort of celebration around this time of year.
It's a cultural thing to others - even non-religionistas often celebrate the Winter Solstice, the shortest day of the year, when the days start getting longer again, bringing the hope of a new beginning.
Most cultures also include the giving of gifts at this time of year.
Now, what has all/any of this got to do with driving?
Only that I suggest we try to give each other some gifts on our roads for the coming year.
Like, how about this "peace on earth, goodwill towards men (and women)" thing. Any chance we can stick to that?
As in, let's stop butting in when lanes end.
As in, let's stop tailgating.
As in, wave someone in from a side street or parking lot. And give a jaunty wave in response when someone performs a random act of courtesy for you.
As in, let's drive right except to pass.
As in, get into the habit of ALWAYS turning your headlights on, ALL the time, day or night, and stop relying on your Daytime Running Lights because it's all too easy to forget to switch on at dusk, leaving most cars without any illumination to the rear.
As in, brushing off ALL the snow on your car, (a) so you can see where you're going and have a lesser chance of running into someone, and, (b) so you won't create a visibility issue when the avalanche of snow cascades off your roof and crashes into the windshield of the car behind you.
I could probably think of a million more, but why don't you add your suggestions?
