It shouldn't be beyond the wit of machine to set realistic averages for country roads, and to allow for probable stops at traffic lights. Pukka Pies might be a bridge too far, though. -- Ian D

We drove from Oxford to Glasgow last saturday. Our ETA on start was 4.15pm We stopped a few times for drinks, food, to walk the dog etc. We lost time during those stops, obviously.. and at road works, but I made up the time on clear runs on the motorway. In the event we arrived at 4.05pm :)) I am not going to complain about that. I have a Garmin Nuvi btw.

You will not hit any bridge pillars if you stay on the road. Bridges are as irrelevant to car drivers as trees. -- Cynic

No, nothing like that. 5 or 6 attempts will usually achieve an adequate performance. About 10 times as many before it starts to become automatic. >I wonder how much time pilots have in the air? No that relevant. There is a saying about 10000 hour pilots - you get one type that has 10000 hours experience, and another type that has had a one hour experience 10000 times. Sitting in the left seat for 10 hours with the aircraft on autopilot is not really flying experience, but is logged in the same way as 10 one-hour flights of a bush pilot. -- Cynic |
