In Houston they try to run across the freeways. I don't know why since it's not like there aren't underpasses at regular intervals, but it seems that every few weeks somebody gets hit by a car trying to dash across I-45. I've seen the aftermath of that and it's not pretty.
I have to admit that one of my worst nightmares would be to be stranded with a broken-down car on a remote stretch of road. No cell phone signal (I don't know if that's a problem in the UK but there are a lot of places here that are too far from towns of any size to get signals), not safe to stay with the car since I'm told that creepy people look for stranded young women, and a long walk to get help. No, thanks. I travel anyway, but it's not a good thought.
Still, 33 years old. That sucks.
