@atpfm those coefficient of drag numbers for flush door handles must be wrong. Only source I can find is this article.

Flush door handles are the car industry’s latest safety problem

China considers banning retractable car door handles from 2027.

But .01 is HUGE, not 1-2 miles. It’s 5% on a .20cd car!

New Model 3 Has

The facelifted Model 3 has the lowest absolute drag of any Tesla, and this has a major positive impact on the EV's efficiency and range ratings.

@atpfm Excellent episode. Made me happy that my code writing days are long behind me.

@atpfm Not that I'm trying to talk @caseyliss into a Porsche, but I wouldn't worry about "replacing the battery" problems on EVs. All EV batteries are warrantied until 100K, probably lasts twice as long, and Casey will get another itch by then.

@atpfm good perspective on AI development from Grady Booch, he’s been doing a few podcasts recently e.g. https://newsletter.pragmaticengineer.com/p/the-third-golden-age-of-software

@atpfm It's very strange to hear the comments about Daikin.

They are the worlds largest AC company by sales and are considered a premium brand, with great longevity and performance. I think half the houses on my street have a ducted Daikin system installed.

@atpfm Regarding @marcoarment 's cold weather/water leak woes, and YoLink's (current) lack of Matter/Thread. The "YoLink YS1606 Local Hub" is coming, perhaps by summer. Details here:

@atpfm YoLink products have proven to be very helpful for tuning my HVAC (w/ claude.ai opus 4.6 assist).

@marcoshuerta If you're referring to the part where I asked @caseyliss to consider how much "replacing the battery" would cost on a Taycan, I meant the (tiny) 12V battery, not the car's giant battery pack.

@siracusa @marcoshuerta FWIW I legit thought you meant the main pack

@caseyliss @siracusa @marcoshuerta If you replace the main one, I'd expect them to throw in a change of the smaller one too. $$$

@caseyliss @siracusa @marcoshuerta I totally knew that John meant 12V and could tell nobody else picked that up

@caseyliss @marcoshuerta Probably because you’re thinking, how much could replacing a tiny 12V battery cost? I dare you to look it up.

@siracusa @caseyliss @marcoshuerta having had to buy a couple in recent years (and watching some car builders on YouTube), I know the answer is “an upsetting amount more than you’re expecting”, regardless of currency

@WTL @caseyliss @siracusa @marcoshuerta Eh, with Porsche nothing is “thrown in”. Unless you count additional lines on the invoice.

@siracusa @caseyliss I got curious and looked it up. That had better be one hell of a battery!

@siracusa @caseyliss @marcoshuerta having replaced a 12v battery in a Macan Turbo I know I saved > $500 off dealer cost by borrowing a programmer from a friend to register the new self installed battery.

@siracusa @caseyliss @marcoshuerta I did. Wow.

@siracusa @caseyliss @marcoshuerta BMWs only fault in this is the non-standard posts they use. But you can easily add them to a normal 12V when the time comes.

@sjtrny @atpfm yup seemed like @marcoarment was saying Daikin was some cheap brand, I was astonished because in Australia it's the top performer, both in efficiency and reliability.

@siracusa @marcoshuerta @caseyliss The issues most folks had were around early software issues that drained it prematurely. I have a trickle charger I bought off Amazon just in case, but I don't typically let me car sit for weeks without it being turned or at least plugged in. After 5.5 years, mine shows 13.5-13.7V in regular use. Ironically, our IONIQ 5 had the same software drain issue…hence, the trickle charger.
