Most can't handle that speed due to the tunnel vision effect. If the jutsu itslef requires the user to move at his top speed, then the roof top battle and Vote 1 and Vote 2, battle have issues with it. In the Rooftop battle, we see Sasuke using Chidori in the middle of the air. In Vote 1, we see him using it while standing, in Vote 2, we see him using it while standing after being beaten, injured and exhausted. So I truely doubt about the top speed requirement.

You can easily trust your arm forward much faster than you can move your body forward, but thrusting your arm forward doesn't increase the overall speed of your entire body. I don't think anyone said it increases the speed of the thrust only. As far as we saw, Sasuke and Kakashi run along with their Chidori, in speed they claim to cause tunnel Vision.

On one hand, the technique causes tunnel vision. On the other hand, the lightning itself isn't channeled throughout the entire body, within their legs, or even into their nervous system to even enhance the user's speed. As far as I can tell, it shouldn't enhance the user's speed honestly, though this contradicts the tunnel vision. *Shrugs*

I never understood why it causes tunnel vision anyway outside of a "useless weakness" because such lightning being concentrated like that could easily cut or pierce the target regardless of speed, fast or slow. Anyway, it is what it is - very confusing. Oh, and the databook doesn't mention the techniques increasing the speed of the arm or increasing speed at all, but whatever. The only 'counter' to this Chidori's speed beinh over the whole bodu is the Lightning Armour argument. But if anyone actually takes a hint, then you can just see why the Lightning Armour out of nowhere was introduced with full on presentation about everything, including it's boosted reaction ability along with it's speed boost. It's to show why unlike the Kakashi or Sasuke, the Raikage can move accordinally without the Sharingan. It's how it was shown.

And there are also some arguments about the Lightning flowing over the whole body. That's the purpose of the Lightning ARMOUR, a full body armour of Lightning.

So far, there's nothing against the Chidori boosting the user's speed, since that's the whole "The Impossible speed it's used" "The Secret is in the speed of the jutsu" point of it. It's easier to assume that the boost in speed causes the user to cross over his natural/maximum limit and thus fall into a tunnel vision. We have already seen many other characters run faster than Lee without gates, and have been told to not experience any tunnel vision. It's just how it is.
