I do not personally know of any taking any . That said, given the rigorous physical, recurrent, and proficiency exams all pilots go through........
I'll take my chances with the guys up front. Most people can't change lanes with banging up another car.
Pilots need to process information, and make a sound, and deliberate decision with no-second guessing. Turning a 757 for finals into Boston with high wind gusts, frozen precip, low visibility...basically ILS conditions is alot harder than making a u-turn in your Camry on wet roads.
Airlines now, make little to no money and there is pressure to get people home, on vacation,to meetings and help the bottom line.
Flying can be and is stressfull. The commercial pilot community as a whole is very good at self-policing themself. Most pilots can declare themseves 'unfit' to fly. ( stress, fatigue, or some simply time-out...over FAA duty time, etc ) Sam Whiskey, I wouldn't worry about your next flight.
But........the FAA and airlines need to do more to help pilots. Today, most are being pushed to their limit, and the up and coming pilots from the regionals do scare me,no fault of their own. It's the safest aviation system in the world ( US ) but more needs to be done to improve it and keep it that way.
