...like the Toyota I drove about in Dharan during GWI which had a notice on the wing-mirror to the effect that stuff seen in reflection was not its true size? I'd have preferred a warning notice on the dash that bozos with tea-towels clamped to their heads with bungee-cords were prone to take short cuts and drive toward you on the wrong side of the freeway at closing speeds of over 120mph....but that's just me.
I know many an EC who got cut on very sharp 1900 covers and utility covers, etc. I called UL about it once, and was told that I would have to send it in to UL so that they look at it. I never got an answer back.
