Actually it would be right up their alley. I've seen people simply scoff at their $200 a month expenditures.

I reduced charge to 50% and plugged in all the time. Li-ions don't like to sit at high SOC and since you're diving so little why bother at 80%

Has anyone noticed any issues with their wifi connectivity after upgrading to 2020.12.5? My car used to always connect to our wifi in the garage with no problem. Now when I get into the vehicle I notice that it refuses to connect to it unless I do a soft reboot of the computer. After it comes back online it connects instantly.

Mines been fine. Reported range is still shit though.

Ok. I left it at 60% but you are right I think 50% is better.

Of course.
You're charging to 50%, the BMS is therefore at the median threshold voltage range where tiny changes in voltage are related to large changes in capacity.
When I charged our Model S to 90% daily for years, it reported 414 km range (out of 425 when new).
Recently, charge to 80% and now I'm seeing 326 km range, which would be 407 km at 90%, supercharged the other day to 90% and got back to 414 again.

Which means, if the battery isn't at a higher voltage, the accuracy of the range calculation is reduced.

Change to % and stop over thinking it.

Not over thinking. You don't seem to understand how range is calculated and I have already stated many times that it is not a guessometer. But whatever you do you, as this has been covered to great lengths on the Tesla Motors forum.

I'm not sure whether it is related to 2020.12.5 (which I have) but I have noticed that during the past week or so the car doesn't recognize my phone very well when I approach. It sometimes takes a few seconds before the door unlocks. It has also started to tell me that I have to place my card by the console to drive. This is recent.

I don't end up getting my card out of my wallet. A few seconds later I am able to put the car into gear.

It is a bit irritating though.

I wish I could report your battery health. My SR+ started at 380 km range at 100% in June 2019.

33,000 km later my 100% rated range (Stats for Tesla and Teslafi are in agreement) is 352 km. That is a loss of over 7.4% compared to your loss of 2.6%.

(As an aside, my driving efficiency is 115%; better than 98% of users, per "Stats".)

My usual charging is 85% to 90%. During 10 months I have dropped below 10% and charged to 100% three or four times to balance the battery cells.

That "information avoidance" is OK for people who do mostly city driving or who are frequently close to a charging station. My driving is usually distance driving of 200-500 km in a day with only one Supercharging station in my area, typically 100 km or more away from where I am.

I need to know how many more kilometres I can drive so that I can always be sure of not running out of charge.

I still need to have certainty that I can get to the next (operating) CHAdeMO station. There’s not a lot of them where I go north of Nanaimo on Vancouver Island.

Looks like FSD may be available on a subscription basis. I barely trust AP but I might try FSD or a month or 2.

Also, automotive margin of 25.5% from today's earnings report. That's pretty damn amazing. As a comparison Ford is at 12.5%, VAG is 19.33%, BMW is 16.66%, GM is 5.61%.

I kept it at 50% for a few days, but my butt dyno didn't like that the car felt slower. So I'm back to charging to 90%, and my butt dyno is happy again.

Nanaimo :) Lots of memories. Did all navy training in Esquimalt a long time ago. Should have stayed there.

This looks like clickbait to me.

I see nothing in the article that suggests that, "Tesla is working on a pay-as-you-go subscription to its “Full Self-Driving Capability” package in order to make its features more accessible."

The article itself says, "There’s code for pay as you go subscription plan, has been for quite a while. Waiting for that eventual time when it will make sense I am sure.".

So code has been there "for quite a while" unused and there is no evidence that it will be used at all, let alone in the foreseeable future.

Effective clickbait, but clickbait nevertheless.
Tesla confirmed it last night

https://electrek.co/2020/04/30/tesla-se ... ice-price/

Musk said:

“I think we will offer Full Self-Driving as a subscription service, but it will be probably towards the end of this year.”

However, both Musk and Kirkhorn emphasized that it will make more sense financially to buy the feature than to subscribe to it:



Musk said:

“I should say, it will still make sense to buy FSD as an option as in our view, buying FSD is an investment in the future. And we are confident that it is an investment that will pay off to the consumer – to the benefit of the consumer. In my opinion, buying FSD option is something people will not regret doing.”

Kirkhorn added:

“Agree. And financially, rolling the upfront purchase of the FSD option into a loan in the vehicle or a lease will be the least expensive plan on a monthly basis to own, plus you preserve the option value of increased value over time.”

That version got retracted shortly after it went mass release... I got it and no issues . My friend never got it and when he pinged Tesla, he got the below response

Stating that range is not a guessometer has two elements:
1. Cars like the Leaf report range based on battery capacity and driving.
2. Cars like the Tesla report range based on battery capacity.

Battery capacity is also a "guess", in that there is significant elements of heuristics involved to gauge the measured cell voltages and conditions (extreme cold and internal resistance).
At 50% SOC, the cell voltages are at a "knee" where small changes in voltage can be reflected in large changes in SOC calculation.
Tesla BMS cannot measure individual cell voltages across thousands of cells, rather, the voltages of a group of cells.
Individual cells are "bled" as the car top balances the pack, so keeping the pack at 50% doesn't even out cells voltages, there can be millivolt differences.
As I clearly outlined, when charging our Model S to 90%, the range reported is ~372km, when charging daily to 80% the range is ~326km and when fully charged (and allowed to sit for a few hours for voltages to settle) 414km.

If you do the math, this has nothing to do with guessometer or other mistaken assumptions you continue to post.
326 is not 80% of 414.
372 is nearly 90% of 414.

Which obviously means, the Tesla BMS provides a more accurate estimate of the percentage of fully charged range (and therefore the km remaining reported on the dash) when the car is charged to 90% than when charged to 80%.

I encourage you to charge your car routinely to 90% and often to 100% like I have done for 5+ years, and you'll stop complaining about the fictional loss of range.

Your data points are a lot better than mine. Look at how erratic it is. Also note the sharp drop when it was still hot/warm out last year.
