I suppose the trick is to know who is a good pilot to learn from. No doubt as with car drivers there are pilots with lots of experience who have developed dangerous habits?
Two questions to answer above
1 - Fuji has given some examples of good pilots to learn from, airline pilots who train for their companies, in my experience, are very good if you wish to learn about becoming more consistent in what you do and making better decisions; this is what they apply as line pilots and educators of other line pilots, they also have teaching skills. I cannot over emphasise what I learned from these people about decision making and its importance in safe aviating
2 - All people can develop dangerous habits in any field (remember its called human factors) One has to learn to make judgments about other pilots. For example, a B52 captain took his crew to the farm a number of years ago by exceeding the aircraft limits, yet he was a senior officer and apparently a very good stick and rudder man, who had handled the aircraft in a similar way before and got away with it - a real hot dog until that final turn

That judgement will come with experience, in the meantime you may have to ask around and average out peeople's opinions
