So, Tesla is gonna have my car for a few days while they work on some stuff. I've been checking on it a few times a day and wonder if things I've noticed is normal. How accurate is GPS? It's looking like they keep it parked in the overflow parking outside. There's a gate, but it's not closed during business hours. Car is never locked. Also, how many miles is a reasonable amount to test stuff that happens while driving? I can't remember for sure, but they look to be at about 30-40 miles in a day and a half.
