I'm planning on the following being in the car: Tesla tire sealer/inflator, Jack pucks, Mobile charger and adapter, some micro fiber cloths, flashlight, tire gauge and a seat protector (I'm a runner and don't like sitting on my car seats when sweaty). I don't drive much out of the city, so I don't need much. 95% of its life will be going back and forth to work. I might get some other charger adapters depending on the trip and super charger availability on the route and destination. I like the idea of keeping a copy of the jack points diagram in the car with the pucks for quick reference. That could prevent some serious issues.
