It was time to swap the winter wheel/tire set in favor of the OEM set. Can’t help but notice the corrosion with the fancy name @MikeGroppX posted about prior! I’m looking for a tire recommendation 245/45/20 summer tire is Conti ExtremeContact Sport 02 best bang for buck?

@europapenguin @GeorgeRoush It’s unlikely the the use of “Hail Mary” would have been a joke. It’s very common in English, especially with “creative writing” to use a phrase that’s informal. The intent is usually to convey a less formal tone

@GeorgeRoush ありがとうございます。もちろん書籍の題名はoperationの意味なのでしょう(日本人はまずこの意味で受け取ります)。わたしが考えたのは、作者にパスを投げることとかけたジョークの意図がある可能性です。もちろんジョークは言語的に繊細なので、英語話者からすれば成立していないものかもしれません。

@SpeedSportLife @MikeGroppX Oh you’re right, I should have known Mike would be in the wrong here…
My bad, I should have known the integrity of the poster. Bro probably even wants to toss RPF1s on it.

Help I cannot stop building the most swagged out forms of transportation imaginable

@jmwilt21 @ChadMoran I do think it’s rather weird to consider it pure human error.
Depends on the study but 0.5-0.75 sec in reaction to start applying the brakes when at full attention then
CT stopping is 126 ft so about 2.8 sec from 60mph. It’s barely enough time in ideal conditions
English
Idk man, 4 seconds before the crash is basically the start of the video if not slightly before the video started. I think this was 100% human error.
And I think we should be frustrated at Fox for pushing the story with clear intentions to have people blaming Tesla without having all the details.
English
I normally don't bother armchair quarterbacking these situations. But watching the Tesla Stans come into the comments is funny. Elon said Autopilot (FSD?) was disengaged 4s before the impact which if you watch the video looks like it was going way too fast at that point. Am I missing something?
Fox News@FoxNews
'TERRIFYING': Dashcam video shows the moment a Tesla Cybertruck, allegedly operating in self-driving mode, nearly sent a Houston mom and her infant off a bridge before violently crashing into an overpass barrier. The woman claims she suffered multiple injuries from the incident and is now suing the automaker for $1 million.

So apparently there’s another (2019) Suburban account on here that’s NOT me and is posting extremely bad content on here, I’m not gonna show the tweet I saw for obvious reasons but it’s not good at all and that account should be reported and hopefully suspended very quickly

Why would manufacturers want to sell directly really? EVs are one thing because the dealers don’t really want to sell. Aside though the manufacturers have it good with dealers.
Julie Chang@JulieChangRE
Something is very broken Time for manufacturers to sell direct consumers. They are selling a product. Doesn’t matter which dealer you buy it from or where

@tomolesnevich My kids can’t quite make a snowball well yet so they have me make them just to throw them at me.
I mean throw them at mom at least

In ten years when jeep mountain forms and the world collectively stares at Gunt because it’s his fault

I love ethical littering (apple cores, banana peels, my broken jeep, etc.), you can just leave it on the side of the road and it will give back to nature, it’s beautiful.

@jmwilt21 @rsuyoy @EricJRacy I have a comparison point between my 32gb m4 and 8gb m2
Over time yea the m2 is demonstrably worse performance.
1) basic photo editing with affinity 2 is fine.
2) video editing that isn’t Final Cut is useless
3) basic coding works fine
4) it’s a competent work computer
English
No, an 8GB of ram laptop is not “only for web browsing”
you can code with it
you can do graphic design
you can do video editing
you can run photoshop
you can multitask
Tech bros are subject to a massive bias where not a single one of them has tried an 8 GB of RAM computer in the last 5 to 10 years because they all default to thinking they’re unusable when they’re actually perfectly fine.
it’s fine. mostly.

An 8GB MacBook is not for you. It's for people who just use the computer as a browser device

2014 press release.
sometimes the internet just isn't the best...

Nokian has invented a new hybrid winter tire that deploys the studs when needed. Hakkapeliitta 01. The studs retract and deploy depending on temperature. Studded winter tyres offer worse grip than studless in some winter conditions, but are superior on ice. I am excited to try these!
English
So, um, things typically retract when it's cold out. What sort of witchcraft is this that has the studs doing the opposite?
cc: @MikeGroppX come talk tires
English
@LeviBetz Yea unless you’re willing to invest. That’s where simulation actually has significant usage. Depends on the region but Europe was about 30k for a mold China is 20-30k. All outsourced. Some manufacturers have it in house
English
@MikeGroppX Yeah makes sense. So you kinda only get one shot at the mold then?
English
This is a prevalent thing in tires.
There’s alot of infrastructure and intentional planning that goes into simulation being useful when compared to the cost (and time) of just making the tires
Groups like GM Motorsport’s Tire Team led by Heather Bobbitt push those boundaries
Phoenix𝕏@Xaraphim
we we figured it wasn’t worth the time to try to run simulations on something like this when we could literally just throw it in the car and run it till it breaks We got the same failure mode basically every time after about 20 hours of race time, In this application, I really didn’t care for the 3-D printed solution. It looks cool, but I think that there were better places to save weight in this application personally It was so cool to do very fun to see it working
English
@LeviBetz Once the mold is there it’s the same as the full production process. Same lines, usually the same components unless you’re prototyping with new stuff but even that is mixed on production equipment
English
@MikeGroppX What's the tire prototyping process look like? I would assume any mold would be extremely expensive, maybe the compounds and bands less so to iterate on?
English
@MikeGroppX but how much of that is actually done by black donuts rather than the tyre companies themselves? they’re claiming 20 out of 25 of the top manufacturers on their website
English
@MikeGroppX also it makes the gt3rs on the budget sheet a worthy business expense
“yes i needed this car specifically to test tires” 😂

I remember service academies running a joint study on this a few years ago, and then absolutely flipping out over the results.
They were doing everything they could to try to get short form video off of the campuses.
I don't know if any of their efforts ever succeeded.

Addiction to short-form videos reduces brain activity in the frontal lobe weakening the ability to focus.
