Tunnel vision starts to occur at about 60mph yes but there are various factors person to person that can effect how much information they can process[] A motorcyclist overcoming tunnel vision by looking left and right doesn't negate the fact that they are losing visual information from their center field of vision. Byakugan has a wider field of vision but not a wider center field of vision. There are a few times in the fight with Kidomaru that he turns to look directly at things that are coming his way. This heavily implies that his center of vision is where his eyes are actually looking. Tunnel vision still applies because anything outside the center field cant be seen.

Even with the Byakugan, the user would have to adjust their narrow center field to see the enemy and even if they do see the enemy they wont be able to see much of them, especially at close range, this is exactly what happened to pre-Sharingan Kakashi.

The chapter where Kakashi talks about the Byakugans perception is accompanied with an explanation of what it can see that the Sharingan cannot(Chakra points, chakra network, etc etc). No mention of extra clarity or clarity of perception at all. Nothing said or done with a Byakugan even suggests additional clarity.

The telescoping function of a Byakugan also wouldn't make anything clearer than it would if the user was close without it. Lets take the camera analogy again for example: A smudged lens will not capture an image any clearer by zooming in on it. The same with an actual telescope. These functions dont make the image any less clear, they just enlarge the image.

During Naruto's fight with Neji, he momentarily moves too fast for Neji to keep track of when he draws Kurama's chakra, and Neji doesn't find his position until he slows down again to a near stop. He again shows no precognitive abilities when Kidomaru suddenly jumps away from directly in front of him without him noticing until he is already gone. Contrast this to Sasuke during VOTE1 where he fights Naruto, who has a bigger Kurama amp than he did against Neji. Sasuke is barely able to keep up with Naruto until he gets his 3rd tomoe and he starts talking about how much more clearly he can see everything to the point of pre-cognition.

Also, when comparing how the manga depicts Neji sees with the Byakugan and how Sasuke sees with the Sharingan, we can see how differently they operate. During the fight with Kidomaru, the manga shows us how far from himself he is focusing and how much space he is looking. Mind you, this is the fight where Neji and his Byakugan are pushed to their very limit. What it doesn't do is show us the kind of per-cognizant vision the Sharingan has like in VOTE1.

Byakugan has actually shown multiple high speed tracking failures, was not said to have the clarity necessary for this high speed tracking, and was not shown to have the clarity needed for movement prediction(which is necessary for Chidori)
