It is an automatic transmission. What other choice do you have than "letting it do its own thing?"
You may also use it as an indicator that something is amiss in the transmission (excessive slipping from a stuck valve or worn plates). It's all a matter of how engaged you want to be in how the system is operating.
I am sure there are millions of consumers diagnosing their automatic transmission that way and that is the reason it is there.
See, it's not so black and white.
From scientific point of view, it absolutely is. The bitrate is a one way measure. It is never meant to be used in reverse to judge the quality of anything. For example, I can take any video and make it run at 100 mbit/sec regardless of source complexity, codec in use, etc. As you watch 50 movies that way, tell me again what information you have gained?
Almost half of my career was spent in the field of compression. Yet, I only looked at bitrate meter twice:
1. When the first Sony DVD player came out. I turned onthe bitrate meter only to find it so out of sync with what it was playing as being more annoying than useful.
2. When BD format came out we were trying to diagnose some bad looking BD title. So we turned on the PS3 meter and found it totally useless and non-revealing. The thing is way out of sync and heaven knows what it is really trying to show. And this was with me and the Phd guy who ran the codec team for me and has 80 patents in his name in video compression.
The above RPM meter at least tells you what your engine is doing. The display here is like showing the RPM for the last gear you were in, with some error thrown in there for good measure.
The information is there if you care to use it.
Well, if experts can't make sense out of it, good luck to anyone else who wants to "use it."
If not, you can ignore it, as well. Dictating or dismissing how somebody else should use it is pretty ridiculous, otoh.
Here is the issue with this number. It appears to be something that is easy to understand. The analogy was made to HP in cars just now. But it is nothing like HP. It is more like revolutions of your car tire or some such thing. Yet, people have been trained during the format war to think of it as horespower. So whether they understand it or not, they are going to think it is important and quickly become disappointed if the rate is low.
Really, bitrate has become the monster cable of video formats. Whatever useful information that can be gained, is long lost due to hype created around it. Yes, thicker cables do carry more current. But they also break your HDMI connector as happened to me
