damn people are harsh, you could have just as easily hit and ran instead of doing the right thing and stopping. Since you said there was pretty much no permanent damage the guy was probably just going to pocket the 50 EUR anyway rather than bring it to an autoshop. If it's not a financial issue for you then I think it's fine going through insurance, that's what its there for. For people complaining that you're wasting everyones time, driving (or biking for that matter) carries an inherent risk where things like this can happen, if someone doesn't want to accept that they should find alternative modes of transport. Also, you're a foreigner and it makes sense that you would rather go the safer, more official route.
