I can appreciate an open conversation about the recalibration but if you don't do the recalibration your sensors will be off until the vehicle recalibrates itself over time.
Why not just recal it after having the windshield replaced? What would the benefit be from waiting for the truck do it over the period of possibly days/weeks?

When you take the camera out of its bracket the calibration is off and your systems like adaptive cruise control, collision avoidance, lane assist won't work correctly and could
potentially lead to an accident for someone who relies on those systems. Btw no one driving should ever rely on those systems ever....

To go off what you said that you absolutely don't need to do the recalibration, correct that you don't have to have it done, but the system will not function as it is
supposed to until it recalibrates itself then.

The reason glass companies do the recalibration is because they get paid by insurance to do it, it's literally that simple.

I disagree. My system worked perfect when the truck was picked up. If the glass is the same, how would the "sensors" be off unless the installer messed with it? Particularly if its OEM glass?

I believe resident expert @Jimmy07 would confirm, there's no reason to recalibrate and many that do have problems after.

The system can work perfectly(or you assume it does ) but it may not be working accurately. The manufacturer recommends anytime the windshield is replaced, tire size changed, or it has been replaced it needs to be programed. The forward.

Why the manufacturer or insurance companies require it, my opinion is that they are covering their *** in case the system fails to work properly after replacing the windshield. If somehow the glass isn't sitting at the same angle as the original then the camera could be off. Then the measured distances by the the DASM would be off.

The camera rest inside a bracket attached to the windshield and it has to be removed to replace the glass, so yes the installer is messing with it anytime they swap out the glass.
The brackets that come on the new piece of glass could be off by a couple millimeters and would then throw off the calibration rendering the previous settings inaccurate and
therefore useless, it might appear that it's working correctly but because it's placement is off, the sensor wouldn't trigger at the correct time potentially causing an accident.

I've been doing glass for years and all while yes we can swap the glass and not reprogram everything and it'll appear to work, in reality it actually isn't functioning as it should.
I will definitely tell you that the glass companies are getting paid a ton just to do the calibration but if you're paying with insurance and only covering your deductible, then
I guess it really doesn't make a difference.
Unless you pay out of pocket for glass and recalibration, it shouldn't make a difference to have it done and to have it done correctly. Just in my experience if you take it to a
dealer afterwards for a recalibration, I don't think having a lift, bigger tires, or lowered makes and difference for their equipment.
