I used to work for insurance in the windshield claims department as these kinds of camera systems were becoming more commonplace. We used to have to tell people that the glass shop could replace the windshield but that they would have to go to the dealership to have the cameras recalibrated since most shops at the time couldn't do it. It's great to see that they are able to reliably do it in one stop now!
Yes I really appreciated they could do the calibration via the mobile visit when they replaced the windshield - no need to take the car for a second step to the dealer
