After the windshield of another vehicle broke by itself on a very hot day,
I learned my lesson, and always leave the windows of my vehicles cracked
open. (It's easier for me to just leave them cracked open all the time,
rather than to remember to open them when it gets hot.) I have rain
deflectors on my Westy windows, so it doesn't matter if it starts to rain.
