As for the technology aspect of the car. There is a learning curve and people should read the manual to start off with and then later as needed. You'd be surprised at all the things you'd learn about the car. Also very important to know how the safety features work and where things are within the screen menu (that you can preset to your desired usage). I did Not find it difficult to get use to Standard regen braking or the screen center position. The OTA updates have been great and fun to get sometimes and on occasion have been a step back which then gets fixed in another OTA update. I love how they introduced TeslaCam and Sentry Mode after I got my car and have seen it keep improving. Certainly has helped many people in many different situations. Just read today how one Tesla owner was able to help out an ICE owner who's car was damaged by a pickup truck while pulling out of a spot next to it and all caught on the Tesla owner's TeslaCam. He sent the distraught ICE owner the video from his camera showing the car being hit and run, got the guys license plate and she was able to go to the police who found the guy and charged him. Saved her money out of pocket she would have otherwise been paying herself on the repair. Just one of many great features I've come to love about the car.
That's definitely something I want the both of us to do once we physically have the car. Take it to a lot or empty area and test out everything. One test drive was enough to get me hooked, but definitely not enough to get used to everything.
I can't wait for the TeslaCam (and the reverse camera, but again that's now a standard feature in most cars that we just never had). I can't even count on both hands how many scratches and dents my car has from being hit in parking lots and the culprit driving off.
