I see it eventually going down the route that if you intend to drive yourself (take it off of autonomous driving) you will have to explain why in the event of an accident. Eventually it will be, you would need a special type of insurance in order to drive yourself.

It is true, the hardest obstacle to overcome the Autonomous driving problem is going to be the other humans. Be it other drivers, emergency personnel, or pedestrians. There is no set of "if thens" that can fully predict human behavior. Right now, I 100% trust my FSDs anywhere where there are no humans ;). But since I live in NY, that never happens.
Yup, and you have humans, and then there are New Yorkers :p They are like London Taxi Cab drivers with ADHD 😬🤣

But seriously, I strongly agree. I trust FSD more as well.
 
This isn't too much information. It's too little.

Temperateure changes pressure needs to be known, regardless of method of checking pressure.
Maybe you have a point. There should be some sort of warning on the readout saying temperature can affect pressure.

You’re right but either too much or not enough information can cause problems. There’s that sweet spot where people know enough information to get themselves in trouble but not enough information to figure out what’s going on. If they’re completely kept in the dark, they don’t know anything is different. The low tire warning light for example that doesn’t give them any indication of a pressure increase. If they know just a little bit more, they know enough to do the wrong thing like the current tire pressure system that tells them the pressure without an explanation other than a warning if too low. If they know everything, they have a full understanding of what’s going on. Maybe there could be an instructional paragraph explaining how pressure changes as the temperature of the air increases. Also explaining the recommended pressure is cold pressure.

Interesting little comparison regarding battery degradation.

This is very interesting. The question I would have is what year model are these cars and how is the battery chemistry in current model year compared to the ones tested at 100k miles. For example if that car is eight years old, I suspect the current battery chemistry would be different. This means it might degrade differently. Theoretically it should perform better but who knows.

I know how much some stress about their iPhone battery health percentage. That’s a $99 iPhone battery. I couldn’t imagine the stress seeing a $15k EV battery degrade would cause. Maybe this is something EV manufacturers will take into consideration when displaying battery heath to reassure people that what they’re seeing is normal. Obviously they will be able to display more information on a larger screen.

Every car I ever owned came with a manual, these things are actually explained in there.

Mind boggling to me, back when I started to learn driving in the mid 70s, one knew to check the oil when the gas was filled up, check the tire pressure too, even check the coolant level regularly, knew, that if coolant level is low, run the engine when pouring water in... Could go on ...

At least on Tesla, checking battery health requires you to drain the battery then fully charge it, which is detrimental on NMC/NCA packs. Without running the test, you are kind of guessing what the state of health is on the battery.

Calendar aging is going to be the largest consumer of pack health. Especially for folks that don't drive far in a year.

You can get an estimate on apps like Tessie or recurrent. I’m not sure how accurate these are though. I’m not concerned about it at this point. Once my warranty gets close to ending, I will assess the condition and determine if I need to have it replaced

I traded my 3 in for a Performance model with like 98k miles. If I remember correctly I think I lost like 10% health. When I cared to track it on TeslaFi it fluctuated between 6 and 13 percent.

You had a Model 3 Long Range? I thought about the Performance model, but since I have Tesla insurance I can’t really do any spirited driving when it comes to cornering and the acceleration is already crazy enough on my 3 LR. Is it your daily driver?
 
So, I finally said goodbye to the Volt and hello to a full EV lifestyle.

The color is called Shooting Star. I think it may actually be Space Black. :D

Same, pretty much. Sold 2018 M3 mid-range at 104K on it, and it was down about 8-10% of charge capacity, best I could figure. Sold it to my brother, so both he and I saw zero issues or concerns. Early gen NMC, and I took good care, mostly keeping it between 80% and 20%, with less than 10 charge cycles above 95%.

Yeah I had the AWD LR model. Loved it but always had Performance model FOMO, so I "traded up". It is my daily driver.

Which generation do you have? I must admit I do have FOMO for both the current TM3 Performance, and also for the 5n. Just want them for a while before moving on 🤣😇

Talking EV’s with my boss. He’s just about to trade his second Tesla.
Looking at a BMW i7 as he misses the premium feel he had in his Mercedes.
i7 is pretty impressive, Mercedes EQS likewise. Definitely a premium feel at a different level. If he doesn't mind standing out a bit, and doesn't mind a more sporty side of things, then a Lotus Emeya is pretty outstanding as well.

Or, if he doesn't mind Chinese, NIO ET9 would be a nice different and luxurious experience as well.
 
Nice, that is supposed to be quite a difference. And then the performance one as well, with those fancy seats?
Yup, the NVH is quite improved. The seats are interesting, I'm thin enough to be nicely bolstered. I've taken a trip to Raleigh with my wife and the seats seemed comfortable enough.

The acceleration is pretty fantastic, though I tend to leave it in Standard as the car supposedly does stuff to keep the battery warm when in Sport.

Did you have AB in your LR?

That is the thing mature drivers do :) Just because you have one of the fastest objects on the road doesn't mean you have to constantly demonstrate it. Just enjoy it normally, and if you know you know ;)

Nice. Is that Matt paintwork?
It's more satin than matte but basically the same. I went in thinking I would get the blue one but once I saw that "shooting star" finish, I couldn't turn away from it. I think it works well with the silver trim on the Limiteds.

I was a little worried about maintenance on it but I've read a lot of reports from people with it that it is pretty durable as long as you don't scratch it. Some people do a full hand-wash routine with foam cannons and special wiping techniques. Others just take it through any old automatic car wash. I'll probably do hand washed in the summer and touchless automatic washes in the winter.
