I have had my Tesla S75D for about a month now and am thoroughly enjoying it. Here are some thoughts on some of the features (design decisions) that I see. What is your experience? 1. The Owners Manual is a must have. I don’t have a paper copy but have a PDF on my iPad. I don’t use the copy on the touch screen unless the iPad is somewhere else. 2. I like the “lock on walking away” feature but it means that I need to remember the keys if I want to get into the car or trunk in the garage. 3. I turned off “auto present handles” because it kept activating in my garage when I was doing other things. 4. I did a lot of pre-trip planning using apps like Evtripplanner and A Better Route Planner but after my first 1000 mi trip, I use only the Tesla built-in Nav system. Now that may change in the future for trips of high altitude changes, complex multi-stops, high winds or cold weather. 5. I gave up using the miles units since actual and rated miles keep changing. I prefer energy percent and try to charge when the battery gets to 10-15% but I stop charging at just enough to make the next stop on my trip. 6. I never charge above 90% daily and only charge to 95% for trips. 7. I find the energy consumption display in the instrument panel is great (like a tachometer). It is not needed in the touch screen. 8. I find the other setting for consumption on the touch screen “trip” (sloping green line) to be useless. That information is already shown in other displays. 9. The AP2 features are good with some caveats. On Interstates and other multilane highways, I use cruise control and autosteer. It works well but I sometimes feel the car is too close to 18 wheelers that I am passing. 10. When I use autosteer, I am ready to take over if lane markings are super faded, if construction narrows the lanes or if construction barrels are sticking out into the lane. 11. I have had a few aborts by autosteer when I try to change lanes on a curve. 12. Also, cruise control sometimes brakes quickly when changing lanes when it sees an object that it thinks is in the way. Because of this, I don’t use lane change if someone is tailgating. 13. I love the Tesla iPhone app. I have gotten my first parking lot ding so am over the paranoia of parking a mile away from the store. ( I still try to park between to luxury cars however).
