Re: Oil Pressure Gauge?
I have a 2016 vehicle. There is no oil pressure gauge. Because...well... let's be honest, if you need it, then you shouldn't have let your vehicle get to that point (i.e. you should know enough to get someone to service it precisely because you never do, or you should know enough to service it yourself).
There's an oil light (although explaining that they occasionally need to check that ALL THE LIGHTS COME ON when they start the car, and then all go out, is lost on most people). There's a rev meter (which I don't understand the point of nowadays, given that there are also gear-change icons as well as this big loud revving noise or stall action if not in the right range). There's a speedo. There's even a thing that tells me fuel efficiency (which I would argue is actually quite useful in this eco-era).
But oil-pressure? Nope. Same way I don't need to know the battery voltage, etc. It's a detail that shouldn't need to be *measured* as part of the normal course of driving operation. I'm sure the *car* might want to know it... does the ECU act on oil-pressure for anything other than a low pressure warning? I don't think so. But I'm sure the car needs to know exhaust temperature, O2 content of intake air, valve timing, etc. I don't. It does.
To be honest, that's how a dashboard should work. The stuff I need to know, only, including a big red light if there's some problem that requires intervention. Everything else is just a distraction. I don't need to know how many emails per second my server is dealing with. But I'd like a red light if - for some reason - it doesn't see any emails for a long time, or if it's hitting overload on dealing with incoming emails.
But people lost that point about user-interfaces a long time ago, so most UIs try to show you everything all the time for no real reason. There's no need for my software firewall to flash for every possible network activity, for example.
If I was in charge of some huge national grid of something, I'd want a red-amber-green of most things. And full statistics collection in the background, obviously. But I just need the red-amber-green. Everything else is detail that you can dig into later if it's more than an intermittent blip.
