marcepochet.wixsite.comEV Chronicles #71 - Polestar Sales Blocked by US Government in 2027Just over 2 weeks ago, we got the announcement that Polestar was not able to get approval to continue its sales in 2027. For those not following, this is due to (I admit, I lifted the following from a Google Search Result) the U.S. Department of Commerce banning Polestar from selling new vehicles in the United States starting with the 2027 model year. The restriction is a result of the "Connected Vehicle Rule," which prohibits the sale of connected vehicles with hardware and software linked to

Quick one here. Polestar 3 Navigation SW doesn't account for ANY wind conditions and ignores the energy it will use for preparing the battery before a DCFC charging stop. Not trying to hate on the vehicle, just trying to keep owners/drivers informed for their own trip planning.

EV Chronicles #66 - I discovered Polestar 3 Preconditioning doesn't always (rarely actually) pull power from the EVSE. Details of my investigation inside the Blog! marcepochet.wixsite.com/the-ev-chron...

marcepochet.wixsite.comEV Chronicles #66 - Polestar 3 Relying on Wall Power for PreconditioningThe reason that I am writing this post is that I discovered over the past week, that my Polestar 3 doesn't ALWAYS pull power via the EVSE for preconditioning when plugged in. I always assumed that all EVs, in order to minimize unnecessary charging cycles of the battery, would pull power from the EVSE when plugged in no matter what. Let's get into the details of how I discovered that this is actually NOT how a Polestar 3 is programmed.I know, before continuing, some of you are thinking...."why

EV Chronicles #65 - Polestar 3 Winter Efficiency marcepochet.wixsite.com/the-ev-chron...

marcepochet.wixsite.comEV Chronicles #65 - Polestar 3 Winter EfficiencyAlmost two years ago, I wrote a blog about the Truth and Lies about EVs and Cold Weather (https://marcepochet.wixsite.com/the-ev-chronicles/post/tesla-chronicles-46-truth-and-lies-about-evs-and-cold-weather).  Two years later, and sadly, not much has changed.  In my opinion, that was one of my best, most details blogs about driving an EV in the winter, so I suggest reading it (again if you read it the first time) if you want to know more about all the factors that go into range loss in EVs due t

He lost an election and refused to accept the results. He forced the Smithsonian to lie about American history. He fired the head statistician bcuz he didn’t like the jobs numbers. He can’t handle the truth. We elected the biggest pussy/coward/sore loser in all of human history.

EV Chronicles #60 - PA to FL and back roadtrip Discussion about our roadtrip in our 2025 Polestar 3 and how family members in a gas vehicle and a 2021 VW ID.4 did in comparison. marcepochet.wixsite.com/the-ev-chron...

marcepochet.wixsite.comEV Chronicles #60 - PA to FL and Back RoadtripLast weekend, we finished our epic trip to Walt Disney World where we spent a week with various members of our family. We had 9 of us in total in Florida with us, all from either Pennsylvania or Northern Virginia (my brother's family). 2 of us flew down and back, and the rest of us drove in 3 different vehicles. My wife and I made the trip in our new 2025 Polestar 3, and my brother's family of 5 traveled in his 2021 VW ID.4 and my niece's 2024 Nissan Rogue.In summary, traveling in a well desi

No, they voted for this and they need to be reminded of it daily so they don't repeat this mistake again. They were either too stupid to understand this was a highly likely outcome, or they knew it was a highly likely outcome and didn't care.

Timothy Burke@bubbaprog.xyz

i really, really need people to understand that they *didn't* vote for this, no matter how much you insist they did. insisting "they voted for this" elides the information environment that led them to vote the way they did in the first place, the thing that actually needs fixing.

Robert Reich@rbreich.bsky.social

If Trump can claim a "national emergency" to disappear legal residents without due process, what’s to stop him from doing the same to U.S. citizens who oppose him? No one is safe — not even people legally in the country, possibly not even American citizens. Fascism is here.

When the grifter has zero consequences for his actions, he is just going to keep on grifting.

Schooley@schooley.bsky.social

Typically, after a grifter pulls a big con they disappear before the marks realize they were taken. I think the thing that’s unprecedented and unknowable is what happens if enough people figure it out but the con man is still trying the same con on them as if they haven’t.

Elon musk is the richest man in the world, he could be funding hospitals, medical research and universities. He could be solving the climate crisis. He could be feeding, hungry children. Instead, he’s trying to make sure that your grandmother doesn’t get an extra dollar of Social Security.
