(Yep - that's "trials riding," and not "riding trials.")
There is a sport in the world of motorcycling called "observed trials."
Unlike most motorcycle sporting events, the object is not to be the first one to cross the finish line. Rather, it's an obstacle course, ridden on very lightweight and maneuverable offroad machines, and the object is to make it through all the obstacles without touching a foot (or any other part of the body!) on the ground, or anything attached to the ground. A judge "observes" how you handle each obstacle, and deducts points if your carcass contacts Terra Firma.
It is quite popular in some European countries. I first became familiar with it as a youth, when I used to hang out at Herb Uhl's motorcycle shop, out on State Street. Long before I was old enough to have a driver's license, I was attracted to motorcycles. (And coincidentally, one of the longest bicycle rides I went on as a kid was one day when my buddy and I rode our bikes out State Street to the motorcycle shops. Carl's Cycles is still there... that was WAY on the edge of town back then. Mom would NOT have approved... so I didn't ask her.) Herb and his sons were trials riders of renown, and ran the shop on the side, where they sold Bultacos... Husqvarnas... Sachs... CZ's... and a new brand of motorcycle - Suzuki.

(There is also a mountain-bike equivalent of trials riding; it's truly amazing to watch a master of the sport, who can wheelie all day long on either the front or back wheel, jump 4 or 5 feet UP from a standing start, etc. Those guys keep me feeling very humble.)
I like to think of winter bike riding as a non-competitive form of "trials" riding. And to enjoy it, you need to have a whole different mentality. Seize the challenge. See how far you can go without a "feet down" event, but bearing in mind that "feet down" is way better than "torso down" hahaha. All the while, you are exercising your bicycle handling and balance skills - think how much more skilled you'll be, once the coast is clear!
They encourage drivers to plan on double their commute time on the snowy days. That's a good general rule for the bike commute, too. But it's not a defeat to take longer... it's a huge VICTORY to push on through! (Maybe it's more like the Iditarod than motorcycle trials. For each day you successfully bike commute, reward yourself with a Milk Bone! hahaha)
