  • I just accidentally deleted my original comment.

    Heres I what I deleted.

    There’s a few things a bunch of other commenters are getting wrong, at least from my understanding.

    The AC compressor is run by a belt from the engine. Unlike a home AC, a vehicles AC is either on or off. There is no cycling. The temp control is just changing how much outside air comes in, or how much heat is drawn from the engine.

    The fan speed is not going to effect anything at all. The alternator spins to generate electricity to recharge the battery, but the amount of energy required to spin it doesn’t change based on how much electricity is being drawn.

    Tamping your AC down in any way, whether by lowering fan speed, or increasing the temperature is less efficient. Use it at it’s coldest temp and highest fan speed if you’re going to use it at all.

    Edit: I almost forgot to add that AC efficiency is going to be more closely tied to your driving speed and outside air temperature. Driving faster makes your AC more efficient (not necessarily your whole car). More air passing over the evaporators means more heat released from your AC to the outside, which makes colder air in your car. The colder the air outdoors, the more heat the AC can release to the outdoors, which means colder air in your car.

    As for EVs, I have entirely no clue, but I would assume it’s a similar situation.

    Edit: I may be entirely wrong. I’m not sure about anything anymore. I know a guy who knows all about these things, let me get him down here tomorrow and we can go from there.

    Edit 2: I meant to make an edit and accidentally deleted my comment. I actually did meet with my guy. Im also too tired to work a phone. Can’t wait to share what I understood from what my guy said.



  • It sounds like you are having trouble accepting that reddit is purely a human user driven, anonymous, and beneficial social media company. I can help you with this issue. Try subscribing to new subreddits. Reddit has thousands of niche communities that cater to anything from cooking, to animated dragons having sex with motor vehicles, to racism, or even knitting! Users are encouraged to post and comment based on a point based system, and moderators of each subreddit work diligently to not only uphold the quality of content, but to tirelessly clear all bot posts as well as any extraneous and subverting advertising. These methods of organization and attention to detail create cooperative and helpful communities that strengthen society. If you haven’t tried using reddit before, download the Reddit app today and you’re sure to make friends and see cool stuff!

  • I have experienced it, and in my experience it was in no way possible for it to be confirmation bias. My wife and I sometimes do something weird where we just talk for hours. Crazy I know, but we bounce ideas off each other to an extent that we get into conversations about stuff we have never talked about nor ever searched for. Not even anything remotely close to related to things we search for.

    We used to have and use a lot of Google home minis. Within hours we would see ads for the exact thing we were talking about. We would see ads for thing related to conversations we had within hours. We started getting hyper vigilant about it. We started randomly talking clearly and loudly about nonsense subjects and products that we have no sense to talk about and waiting to see how long it would take to see a suggested ad pushed to us by Google. It usually took less than 24 hours no matter what it was. This went on for months.

    It became a running joke to us and I would walk into the room and say something like “I would love to buy a farberware brand vegetable peeler. There is nothing more that I would like than to purchase farberware brand appliances and homewares”. My wife would laugh, and usually before the end of the night I would have large targeted ads on my phone for farberware appliances.

    Honestly since we stopped using the Google home minis (since they barely work with anything due to googles bullshit software support) it happens far far less.



  • On a tangential note, this is the same reason I will not buy a phone without expandable storage. The cheapest statistic of a phone is now the difference between a $800 phone and a $1200 phone. For $30 I can double my storage, but that is not ok for manufacturers, especially when they can make $5 a month for 1G of space, that requires internet access, from millions of people. Learning that most people have to pick and choose memorable pictures and videos just because they run out of space is horrendous to me. The companies know that data storage will increase over time for every user, and they are banking on everyone banking their data in a more insecure manner, with them, at an ever increasing rate. I refuse to have my memories and heartfelt data held hostage by bullshit companies that can’t even support their own devices for more than 5 years.
