Hi everyone. I've just joined the community, and so hope to contribute as a traffic technology engineer who is really enjoying his Tesla 90D with Auto Pilot (AP). After about 4,000 miles on AP, I thought I'd share some of the 'tips and tricks' that I have learned in this the 80 hours or so behind the wheel on AP. 1) It takes time to understand Auto Pilot: You need at least 1,000 miles on AP under a variety of weather and different road to get fully comfortable when the care will drive well, and when it will drive badly. 2) The real benefit may be to older drivers: As an older (58 years) driver the main benefit of AP to me is the reduction of work load, and increased safety, on longer drives. I can now do long cross county drives without feeling exhausted. It has made a HUGE difference. 3) Make sure the windscreen over the camera is spotlessly clean: I have just completed a drive into rural Georgia on rural roads, and for a while was convinced that v8.0 did not drive as well as v7.1 (my car updated this week). It would regularly lose the right hand line, and wander more than usual. I then noticed some windscreen streaks in the sun, and stopped to clean the area over the camera with some wipes. It made all the difference! The line recognition was back to normal, and it showed that very subtle streaks on the windshield over the camera was enough to impact the AP line recognition. 4) Get comfortable with AP gradually: Start with freeway driving. This is the easiest environment for a new driver to get comfortable with AP. Then progress to 'stop and go' traffic, which AP also handles very well. Finally experiment with rural roads, where you have to watch out for bad lines, traffic lights, and stop signs (which AP does not process). You can get some frightening experiences coming around corners, to discover stopped traffic ahead. Don't put yourself in these kind of situations until you are experienced with AP.
