Water won't be cool either. And how bad should it be to not sort out "being stranded" by late morning? I mean you're avoiding traffic by driving between 3:30 and 7:00 on weekends (as I sometimes do), so the regular traffic is rather high in your area, you're not going off road and don't drive much longer than an hour one way. In other words, with these prerequisites it's really hard to get into a situation that might require emergency water. Are you in Australia far from major cities?
