Breakdowns

Headed off down south today for a family visit. I don't know about you, but I'm noticing a lot more broken down cars these days. Time was when during a long-ish journey you would see two or three people stranded forlornly at the side of the road. But until recently you hardly saw any. Nowadays they seem much more frequent. Are cars getting less reliable, or are people not having them serviced as often as they should?
