Having just waited 2 weeks to have a windscreen replaced, because the car needed ADAS (automatic driving assistance aids ? - adaptive cruise control, lane departure warning etc etc) calibration, I am curious as to what's involved, and how badly an uncalibrated system might be ?
The whole thing seems to revolve around the fact that pressed against the windscreen is a **** off camera which looks like something out of a 1960s jet fighter. It's almost all heatsink.
Apparently this car (Citroen) needs the calibration done "on the road" - it can't be done in a workshop.
I would have quizzed the technician, but the car was in storage while we had a replacement.
I'm trying to understand how the system can be so sensitive that the slightest disturbance to the camera requires a recalibration (as the leaflet left behind advises).
