Run into a store, deliver stuff - would be so much easier than having press the app every time (which takes forever on my android phone to wake it up). When it's 115F, just one minute with no A/C really matters. Overtemp won't fix it, 105F is still toasty, but I have yet to get that upgrade feature on our M3. Don't want to waste energy either so there should be an option (how does the car know you'll be right back - either tell it, or driver settings?) Other work-arounds maybe?
