Well, hell.....if you went to 'Ford Dealership NASCAR Driving School', then you will surely not have any issue driving a Viper in any conditions......
Really, from the get go you are asking how a car, that is just now being delivered to customers, will act when driving in extreme cold conditions. Who do you figure will be able to get you an answer other than pure speculation ? Ask these questions after next winter and you may be getting some real life feedback.
Are you on the Vette forums asking those guys how the new ZR1 will be acting in the cold conditions as well ??
You keep insisting on bringing up your Shelby as a comparison yet seem to fail to realize that these are two completely different vehicles. The Shelby is an overpowered muscle car (and I like that for what it is) and the Viper is a extremely capable high performance car.
For some reason you have it in your mind that it will be such an easy car to drive. I am not sure where you are getting this idea from. As suggested before, if you can not get to drive in a Gen V then try to get a ride in a Gen IV. You would get a first hand experience on how mind blowing these machines are.
Then when you have that behind you, you will be able to take in the feedback from all those that are now getting theirs V's and comparing them to the IV's they have or had. This will get you a better idea of the differences.
Bottom line is that you need to get behind the wheel (or passenger seat) of a Viper....any Viper, so that you quit making all these assumptions on how you think these car work based on what you 'have heard' or read.
