Very impressive!
Saw one late Saturday night just south of Sioux City on I 29. It was snowing quite heavy at the time and the snow plow trucks weren't fast enough to clear both lanes.
There must have been at least 5 inches build up on the fast lane which most drivers avoided. I was behind the big rig on the slow lane, following his tracks at about 45 MPH...cautiously. Suddenly, here's this Promaster passed me to my left on the fast lane and must be doing about 60 MPH.
.....I was waiting for him to do the fishtail or may be a Tonya Harding's triple Axel jump or something. Well, it didn't happen. The Promasters drove like the "pro" and disappeared into the pouring snow. Or, simply this dude could be crazy as heel, lol.
