I’m not sure if you’re trolling because that’s one of the dumbest things I’ve read on this forum.
Speed literally tells you nothing about how you’re cycling. There are things called hills, headwind, tail wind, poor quality road, smooth road, etc. that all affect your speed. You have no control of your speed other than your power and position on the bike. This is not a metric that any serious cyclist pays attention to when racing other than when they’re bombing a hill and are curious what their speed is.

All of the other metrics are in service of SPEED. You don’t win races by having the most power, or the lowest HR, or the best IF, you win races by having the fastest speed. Just a glance at speed and power gives you a very good idea of if you should push more or back off in the current situation. Bad road surface, headwind, false flat, push a little bit more. If you know you’re normally at 25mph/250w and you see 24/250 it’s a hint to up the power just a little.
I must not be a serious cyclist because I value speed on the same level as power and HR for a TT style race. If you only have one thing to display I’ll grant that power is more important, but on a display with minimum 4 metrics speed should absolutely be one of them.
Tangentially, speed as a training metric can be incredibly instructive. Take a look at the way pure cyclists carry themselves through corners and technical bits in comparison to triathletes. They carry speed, they accelerate harder out of corners, they take different lines. The power/hr can be exactly the same but one can carry extra mph.
This is how you blow up during a race. You train to hold a certain power for a certain time. Going into a race trying to hold a specific speed is not a smart plan.
If the road sucks and your speed is down you’re going to end up pushing to hit your speed goal and you’re going to blow up. You have 100% control over your race effort. You do not have control of what speed that effort gets you.
Find me a coach who preaches going into a race with a speed goal vs a power goal. It’ll wait…
Your anecdote on cyclists cornering harder and accelrating harder holds no ground. Triathletes don’t corner hard because they don’t train bike handling as much as pure cyclists. Sprinting out of corners has more to do with staying on people’s wheels than it does getting the best time. Watch UCI pros time trial; they won’t be sprinting out of the saddle coming out of corners.
