This. Also I freeze the food going in the cooler. So I am bringing butter or cheese or meat, I freeze it first. Then it's already very cold in my cooler. I add frozen water bottles to the bottom and top. Make sure the cooler is FULL of cold food, that helps too. Otherwise, use a towel on top of it all. Air space tends to warm faster.
Then don't open the cooler on the drive. I also wouldn't leave the car off and sitting in direct sunlight for hours, but for a short bit it's fine. My food is always still cold on arrival, which is normally 6-8 hours after I packed the cooler that morning.
