Many years ago, it ocurred to me that FWD cars should be parked with front wheels straight-ahead. This was after I saw my CV joint boots develop a strong "set" when allowed to cool down in a wheels-turned position. They can then flex in a very contorted way when rolling again, until they warm up.
So I've parked with wheels straight ahead for 10 or more years, and haven't had a split boot in that time.
I do realize that there are other potential hazards for them, like stone damage.
Comments welcome.
