Please note that all of the comments below are my subjective opinion based on the first several hundred miles of ownership. My 2018 Model 3 VIN is 39xx. I’m located in San Diego. My other cars are a 2016 refreshed Model S 75D with AP1 and a 2016 Volt. I’m on the list for a second Model 3. The Volt and the Model S will go.
Lane departure warning is totally irritating on winding roads, as it will not allow you to cross the apex of a turn without getting the vibrating lane departure warning. I had to turn it off. (Note that this may be no different than on the S, but it was more noticeable to me.) I’d like an option to have lane departure warning active when on freeways and off otherwise.
You really should use this as an indication of you driving improperly instead of the car doing something wrong. Please keep everyone on the road safe and stay in your lane...Yes, even on tight corners.
