Shopping around recently I noticed that several policies have an upper limit of a few hundred euros on windscreen claims.Do newer cars have more complicated windscreens (sensors etc). A mechanic told me to replace some windscreens involves recalibrating the camera system on the car. So for newer cars windscreen cover is probably worth it.
Stuff like windscreen cover, comprehensive cover etc may be justified where it's a really expensive car and/or one cannot afford to just pay for repairs but otherwise they seem a bit pointless to me...
