ALERT READER COMMENT
As an above-average driver, I nevertheless screw up occasionally. I've long thought that we should carry signs that say "SORRY" both frontwards and reversed (to be seen in rear-view mirrors) that we could hold up when we inconvenienced another driver. I bet this would do a lot to combat road rage. Maybe you are the person who can get this movement onto American highways.
The Stealth Bloggerette thinks this is a great idea, except that in Miami, the sign would also have to say "Lo Siento," "Mwen Regrèt," "Mi Sorry," and of course "Tipiyokti."
