Not a Tesla owner, but that Cabin Overhead Protection feature is pretty cool (pun intended).

Yes, I wonder if it detects something living is in the car? A baby, a dog... Does the car have the sensors to tell?

No sensors, you have to set the high and low thresholds manually.

So, does that mean its constantly draining battery when parked? Is this drain significant?

"Tesla keeps temp below 40C/105F by automatically venting cabin & turning on AC when needed. Can do this for up to a year on a full charge." https://twitter.com/elonmusk/status/778602694399320065

Well, sure, if it's 72 and partly cloudy out. My car can do that for years by leaving the windows open. This feature only really matters when it's swelteringly hot out.

What if I park a black Tesla at the San Diego airport for a week-long vacation, and it's 100 degrees and unmitigated direct sun? Will I come back to a battery that can't get me home?

That would be when I would want this feature to avoid damage to my car from it overheating. But also when it's most likely to run down the battery.

Luckily, there are 42 EV chargers at the San Diego airport for use (free with parking fee). Simply leave your Tesla plugged into any one of them.

And send someone to periodically feed the baby. (Although it would be nice if Tesla eventually offered this service.)

Isn't "up to a year on full charge" also the longest you can leave a Model S parked before the battery goes flat and it's bricked? It does sound like they've calculated their figures based on the cooling never actually kicking in.

Not even. You lose about 1% per day, and then the manual warns that it's bad to let it sit for more than two months after it goes to zero. That's about five months total, if you start from 100%, before something bad happens. I don't think they specify exactly what, but better not to find out.

If it can handle a year on a full charge, then unless your battery is below 2%, it'll last a week. And if it was below 2%, you probably wouldn't be able to make it home anyways.

The parent's point is that the circumstances would dictate how quickly the battery drains, so it wouldn't always last a year on full charge. (And therefore not always a week with > 2% charge.) That said, it's not trying to keep it chilly, just not deathly hot, so I expect it would still be fine.

Right, but it also shuts off at 20%, right? So it won't drain your battery anyways

I'm surprised by that, my 2006 Prius has internal sensors for activating the theft alarm, with a button to disable if you're leaving things that move inside.

Yeah but then you accidentally kill your sleeping baby because it doesn't activate.

I suspect they considered it and decided not to do it because the safety threat of a minute mistake is just too high.
