I prefer blind spot mirrors or segmented mirrors. I can't work out why they're not popular in North America, but the last two British cars I owned had them as standard. Two mirrors = no blind spots. The biggest reason why I don't like angling the mirrors outwards is because it reduces visibility close to the rear on both sides - just large enough for a cyclist to sneak while waiting at a junction.
