I think you can best assess your needs by asking a few questions....
How long will you be owning the Tesla?
You current auto, how many rock chips are on your current car? And over what time period?
What kind of personality type are you? Will a ding or chip really bother you greatly?
I feel that your honest answers to these questions can guide you along the way. Film protection, especially those films that self heal, are the way to go for those of us who want the most protection.
