An insurance is ultimately a guild where Hans stands up for Franz and Frauke for Hauke. - If one causes too many damages, the others pay for it. Therefore, it makes sense, even if in individual cases as described here unfair, for a company to develop mechanisms to kick out lazy customers. Otherwise, it burdens all the others. I like to choose insurances whose distribution channel does not run through verivox or the like, because in the end you pay for the contract shoppers or the smart "I just need to have a claim, I've already paid for 10 years." types. my/our insurances are all broker insurances, whose distribution channel consists only of independent brokers. Thus, their customer portfolio is mainly a mix of freelancers, self-employed, and civil servants. This is a guarantee for good premiums and solid management by the companies. Therefore, for cars we have Condor, for the house the Badische Allgemeine.
