I freely admit I drive an imperfect car- it's old enough to drive itself. And has the health issues to prove it. :P

And actually, I would think that it would get quite a bit warmer over the long term under the hood. I've lifted the lid in the rain and had the drops hissing and sizzling when they hit stuff- I haven't fried yet in the driver's seat. Arm has gotten sunburned a few times, but thats it.
