Well said!

Those numbers don't really change when you're "just driving", so this point might be moot. Personally, one of the things I really like about my BRZ is how fun it makes my commute, and I'd actually prefer the numbers to flash at me (within reason), as in your "market research" point above.

I do understand this can be different for different people and in different situations. Besides making this a user preference, they could also use different parameters in Normal and Track modes.

Without any cameras involved, the BRZ/86/FRS refresh rate is obviously slower
than 24 Hz, at which point using a 60 fps video should be sufficient.

I don't have a recent experience driving a Ferrari to say for sure how their
digital speedos work. Judging by that 30 fps video we can see at least a 10 Hz
refresh rate, which is all we need to know in the context of this discussion.

Shutter speeds are an interesting argument that could be important in some edge cases,
but I can't quite imagine exact conditions that would be needed for us to be wildly
incorrect in our estimations of refresh rates here. Slow shutter speeds would cause
obviously overlaid numbers (which I have accounted for in the Ferrari video)
while fast shutter speeds could skip some numbers, but we'd still see at least
"fps" updates per second if this somehow was the limiting factor.

Missed that. When thinking about shutter speed, it was more in regard to how people might be perceiving the way the numbers are displaying. Like perhaps there is something that appears off when it is probably quite pleasant in person. To me, some of those videos certainly looked "strange." It could that they are like that in person. But I'm not so sure. So I was thinking camera set to "Auto" doing its things.

An example below - discussing shutter speed may not really be relevant as I'm not sure how it would affect the numbers.

Oh gotcha, that's a good point wrt subjective perception.
I thought you were trying to say our estimations of the refresh rate might be wrong.

Do you know anything about it?

Anyway, I can't wait for more news.
This may answer your question. 15:35 into this video is a close up of the dash during revs



Also, an orange shift light confirmed, as seen in this picture.

That's a tachometer though, not the speedo.
The speedo on that section of the video just shows 0

I think the tach and speedometer are on the same screen so the refresh rate should be the same.

Refresh rate of the “screen” is probably 60hz. That doesn’t mean the data will refresh that fast. I suspect they will limit the speed updates just like the 1st gen. I’m fine with that as my eyes are on the tach when accelerating, not the speed. If I’m looking at the speed it’s when I’m cruising and just making sure I’m not speeding (too much). I never even put any thought into the refresh rate of the digital speedo in my car until I read this thread. Hahaha

Let me say I can't wait to see it live. We have infos with the dropper, the time doesn't flow. An easy way to spend time is trying to snatch little car details.

This topic, compared with the old gen, has a huge point: the speed needle of the old gen, that gives you acceleration and brake progression, you don't need that stupid digital number of instant speed and you don't care about its implementation.

In the second gen, I don't know why, they removed the needle, so that stupid slow digital number of instant speed became the only one way to keep an eye on instant speed. This is for me (and a few other ) a little disturbing.

I hope in some software tuning to show the real instant speed.
That slow data update, like an aliexpress speedo of 2$ for bicycles of 50$, is crashing my brain, I'd add it to the compilation of unsatisfying moments:

Just how much time do some of you guys spend staring at your dash to even register gauge refresh rates? I doubt I look at the dash for more than 10 seconds total for every hour of driving.

"OH cop ahead"
.005 second glance at speedometer
"I'm good".

As far as the tach goes I don't care what it says. I can tell if I am where I want to be from the sound and feel. In fact when I teach somebody how to drive MT the first thing I do is tape up the tach so they learn to drive by intuition not staring intently at a gauge.

I don't, I just accelerate until I need to decelerate.

Same here. The only time I do any staring at the gauges is when drag racing and I'm trying to shift right at the fuel cut. In normal driving it's all done off feel and sound. I'm trying to think back of when I was new to driving and I don't recall ever having an obsession with the speedo. The sensation of speed for me comes with the seat of the pants not a number rotating at a high rate.
