The frunk isn't insulated. Thirty bucks at Walmart fixed it.

I wrote earlier about pouring ice straight into the frunk, and I stand by how good that felt right up until physics weighed in. Here's what I know for sure now: that tub is not insulated. At all. It's a plastic box riding in the nose of a car that's been baking on July asphalt, and the instant you put loose ice in there it starts melting, and not at ice-chest speed either. Accelerated. The heat soaking off the body of the car sees to that. So in the middle of the trip I fixed it for thirty dollars. Three soft-sided cooler bags from Walmart, ten bucks apiece, loaded with ice, zipped shut, set side by side in the frunk. They're squashy enough to conform to the tub, they fit like they were made for it, and they kept everything cold clear through the hot part of the day. Tesla will happily sell you a molded frunk cooler for a couple hundred dollars, and I'm sure it's a nice piece. But the three bags did the job, and when I got home they emptied out and folded flat on a garage shelf, which is more than any hard cooler I've ever owned can say. That's the whole tip. Insulate the ice, not the car.
