I drove a Speedster from LA to Salt Lake City several years ago in the dead of winter. It started snowing just above St. George, and by the time I hit Beaver it was coming down in sheets. Presently, I determined it would be prudent to put the top up, and turned on the defrosters "that always come on" but never with actual heat. [I have noticed that these cars have heating systems that work really great in the summer.] I quickly went for the wiper switch, flipped it. Nothing happened.
Fortunately, a sand truck came by in the left lane, and sprayed sand on the road, as well as through the driver side curtain. This sand mixed with the melted snow in my lap giving me a frozen, yet gritty feeling in my unmentionables (crotch), and damaging the paint on the nose of my pretty little car. ($700 bucks front end repaint). (they don't spread sand--it's more like coursely ground pebbles. Thousands of little ping marks.
After pulling over, was able to loosen the wipers from the lumps of wet snow, and get them working. The storm had let up a little, so for the balance of the drive through Provo and on up to South Salt Lake, I was lulled by the sand pinging off the finish of the car, and intermittedly by the back flush of a twelve foot snow plow banging against the side curtain.
Not unlike those few times (ah, more than a few) when I had to follow taillights to maneuver my way back to "she who must be obeyed" I latched onto the taillight of a giant SUV, and followed her on in, to Salt Lake. A lovely experience and I highly recommend it. Don't worry about the wipers, as they are a relatively minor glitch in the trip through hell.
