The Byakugan gives you insight into more than just a wide field of view. It keeps track of every single thing within that wide field of view. I wouldn't call that ESP, but it's more than normal sight does. Normal sight only gives a precise look at what's in your fovea. Peripheral vision only gives you general ability to somewhat track motion with lack of detail. Having a Byuakugan is like having a near 360° fovea.

Hence normal ninjas get tunnel vision at high speed. Neji blitzed Kidomaru and never had to worry about tunnel vision. If Ao had died and Kakashi had gotten to his body, he could've implanted his Byakugan and never had to worry about Raikiri induced tunnel vision again.

Neji in particular also demonstrated the ability to glean information about a persons mind state just by watching them with his Byakugan in Chapter 78, when fighting Hinata. That's clearly more than just a wide field of view. It's possible that this could aid you in manually figuring out what someone was about to do, but that's speculative and wouldn't be automatic, like the Sharingan. It's like being given an unusually large amount of information on someone and using logic or experience to ferret them out.

Again, I don't think that's properly termed extrasensory perception, which usually refers to a sixth sense, so I can't quite agree with the OP.
