...like if, as in my case, some truck throws up a giant rock and the impact is so loud you almost drive off the road... Driving back from Fry's Electronics in Roseville, CA to Reno along Highway 80. POW. Big divot out of windshield, crack was 2 feet long by the time I got home. No problem! Call Tesla, nice person from Gigafactory comes out with a flatbed truck to take my car in for repair (the Gigafactory has a repair center, although you can't visit it personally). Got an email estimate for $1200 or so the same day. Fortunately I read the estimate details because they included a "rain sensor" replacement for over $100. Now, as we all know, AP2 cars don't have rain sensors (wish they did, because the "let's do some image analysis and figure out if we're trying to look through raindrops" feature doesn't work as well, but that's another rant). Called my service advisor and reminded him that AP2 cars don't have rain sensors. Oddly he seemed a little confused by my assertion but did eventually agree to remove the charge. Got car back the next day with new windshield, all is good. So should you ever need to replace a windshield on your AP2 car, make sure you're not charged for a rain sensor.
