Maybe not everyone uses it the same way but to me judgement in this context about values, risk appetite and empathy.
I just signed my youngest daughter up to a pretty extensive defensive driving course at a regional racing facility. When she's done, her skills will have improved but her judgement will be largely unchanged. If she was going to speed before and value her time over the safety of others around her, the same will likely be true afterwards. Fortunately (unlike her sister) she has taken after her mother and proven to be an extremely cautious driver. Her sister drives a smidge too fast for my liking, but we're working on it.
They seem to heavily overlap. I ride a motorcycle and move through traffic quickly. Is it skill? Or that I can judge the flow of traffic, that I do not ride next to any vehicle (or in their blind spot), that I slow down for intersections, especially blind ones or if I do not have a car with me to discourage a left on green.
I just don't see much difference. I consider good judgment to be inherently baked into driving.
Someone exercising poor judgment is not a skilled driver.
