That is certainly a perspective.
Another perspective is that the vast majority of drivers over estimate their driving ability rather than under estimating, and drive more aggressively than they should for conditions vs too conservatively.
Yes, the vast majority of drivers overestimate their ability (or at least college students do:
https://pdfs.semanticscholar.org/ad37/e00352406dd776bc010769489b2412951c7d.pdf). I thought I'd seen a slightly less dramatic report (something like 70% of all American drivers rating themselves as above average) in the news a few years ago, but I can't find a reference online. I'm actually very curious as to the impact the greater cultural penetration of rally driving in Sweden versus the U.S. might have on those statistics.
I'd put at least a fair bit of the blame for that on our so-called driver-education system, which teaches traffic basics and DUI laws with grossly insufficient actual seat time and roughly zero attention to anything beyond basic driving techniques (having "steer into the skid" in the manual doesn't count). Knowing how to throttle-steer a RWD car, when and how to left-foot brake (especially an understeering FWD car), etc., should be general knowledge for the driving public, not esoteric knowledge outside of performance-driving hobbyists.
And yes, in the process of learning how to do those things, you're going to get things wrong sometimes, and that's going to result in going places you weren't planning on. Just like we all fall down learning how to ski, mountain bike, ride an ATV, or other activities similar to driving a car, you're going to have failures learning how to drive. Having a venue for learning that allows you to make those mistakes without a large penalty—whether it be a properly netted ski hill, a road track with good run-off, a frozen lake, or even just a large, snowy parking lot—is, of course, the best way to do so.
And a further perspective is that the person behind you doesn't know that you're a varsity level driver, so regardless, you should avoid intentionally doing things that can distract them from attending to other hazards.
Being able to apply a bit of oversteer on a snowy road is hardly a varsity-level skill, and if it's that distracting, the person in question needs to get out of the house more. We're not talking about pendulum turns and four-wheel drifts at speed.
