Yoo be right Mr 44 cepting............................if you do quite a few hours and are getting towards your limit and have to travel somewhere, our "Authorities" tell us if you fly privately that must be included in your flight and duty times. Say 3 hours in an aircraft is included and could put you in a "Dangerous" flight hours total but driving a car all night is quite acceptable? Another example is if you enjoy flying for recreation and fly professionly getting towards your limit, if you enjoy say gliding and spend your day off gliding, some "Authority officials" want you to include that time on your work flight and duty times.
