Not Quite Right

Most of you know that I've got a personalised plate - CMATGO. But as much as people find that one good for a giggle, there are others out there that are just outright hilarious. Well, they are if you've got a mind like mine.
Unfortunately I wasn't able to grab a photo of yesterday's example, due to my phone battery running flat, but it's easily described. Black Subaru Legacy wagon, with the plate "LH RH". Obviously they're concerned about the intelligence of drivers behind them. Or they're being mean to dyslexics who are travelling in the opposite direction...
