Relax, they don't. The well-worn litmus test in these cases is whether the law was written to target religious conduct in particular (e.g. Sikhs can't wear turbans in public) versus a law that applies indiscriminately (like the speed limit) that some people try to evade "on religious grounds." Obviously, the entire edifice of the law would collapse if anyone could exempt themselves from any part of it on the authority of their own incontrovertible say-so.
