I almost never ride Metro any more. Once in the last year, and less frequently than that in the last 10-15 years. Expensive, crowded, inconvenient, unreliable and unsafe. And all those germ-carrying people coughing on you. I didn't get sick a single time this year. Also, if there's ever a terrorist attack in DC, it will probably be in the Metro system. Metro's woes give me yet another reason to bike commute.
