Quick follow-up on this subject...
I've been researching it a bit and (as per dawiz) not only is overseeing a red light considered gross negligence per Swiss law, there is a whole littany of other things which is also considered gross negligence, like...
- Failing to yield, pretty much anywhere (stop sign, yield sign, white "stop" line, etc.)
- Speeding / not slowing down enough as per conditions warrant, etc.
- not wearing a safety belt
- using a cell phone w/o handsfree
... in other words, just about anything which breaks a basic traffic rule.
Sooo, I'm pretty much stuffed here. However, I will try to argue Generali down a bit, since there were a lot of mitigating circumstances, and 25% is at the top end of what they can reduce it by even in normal circumstances, as far as I can tell. I found one BGE (114 V 315 under http://www.bger.ch ) which, if I read the German legal-ese correctly, suggest a 10% reduction of coverage for running a red light, and one of the books in the "Ratgeber" series suggests that "in normal conditions", running a red light will result in up to 20% reduction.
So, one last letter to Generali -- I think it must be within my right to insist they provide some sort of "proof" (e.g. BGEs from similar cases, etc.) that 25% is justified in this case.
Meanwhile... be careful out there!
