Well, that's actually a problem: if you are forced to use something like OsmocomBB, law enforcement will be more than glad to see they have a new reason to have you in jail.
I'm not convinced that you're average beat cop is looking for OsmocomBB on your phone in order to trump up a reason to nab you. The tried and true method of following you for a couple blocks and interpreting traffic laws strictly is sufficient and requires much less knowledge and work.
