Will a cooler sufficiently buffer out the highs and low extremes in a car during the summer and winter such that medicines and other things won't go bad? Say you use the car nearly every day, but it sits for a couple days on weekends.

What about a yeti / ozark trail vacuum thermos with the medicine in there, inside the cooler?
