I do my commuting solo (home to Metro and back) on not all smooth or straight roads. The passenger side seat belt buckle was driving me crazy banging on the hard plastic door post. This is two layers of self-adhesive felt from Jo Ann Fabric that has solved the problem. Color is not a match, but what they had. I'm not sure what $2.50 converts to in Kronas, but I'm guessing it may be enough to break the bank.
