Prius poses a risk for adulterers

I searched to see if this was posted, and was surprised not to find any reference (so aplogies if I missed it) - on Monday's evening's "Two and 1/2 Men" show, Charlie Sheen's character's illicit rendevous with a married woman was interrupted and how he could've been shot when "Her estranged husband glided into the driveway in his freakin' Prius" and the only way they knew he was there was because the husband stepped on the cat's tail.

I think this might indicate the growing popularity of the car; I've also seen it on "Num3ers" and in the movie, "Must Love Dogs" & "In Her Shoes" - I've also seem quite a few in the background on other tv shows.
