If you are the lone occupant, you would be breaking the law if you used your cell. By the time you find a place to pull over what are you going to tell the police? Also many of the witnesses might think that the bike passing was an isolated incident not knowing that it continued on for many KM's.
I don't get this. You'd call 911 (without pulling over, because nobody pulls over to use their phones, who are we kidding?) and you'd say some idiot on a blue motorcycle just blew through westbound traffic at 200KMH. You'd describe the colour of his jacket and the colour of his helmet. If you know anything about motorcycles you'd identify the make and model.
If we're playing the "Victorians are less likely to call 911 than folks in other places" card then I'll generally agree, BUT this was a supremely dangerous and obvious activity, in broad daylight, in front of many dozens if not hundreds of witnesses. Nobody called? I just can't choke that down.
I'd bet a donut there's some jurisdictional issue related to 911 and the calls were made and they're just sitting in some archive somewhere. It makes me think of that famous abduction case in Florida and how the 911 calls were fumbled royally:

If police are indeed inclined to dismiss incidents like this as "one-offs" then the police response (or lack thereof) is part of the problem. You don't have to chase the guy. In a case such as this, you shouldn't chase the guy. But you absolutely must call it ahead, and you absolutely must document it as thoroughly as you can. Otherwise, the next time that it happens will be the first time all over again. If he causes a terrible crash at some later date, then you'll sure be willing to spend a lot of time and energy on damage control, acting like it's the first time that you've ever heard of this clown, when it actually isn't the first time.
Anyway, I can guarantee you this guy didn't head all the way back to his garage at 200KMH. He slowed down eventually. He resumed normal driving eventually, stopping at lights and all the rest. Maybe he stopped at a convenience store. Call it ahead and there's a chance that another unit will observe him/intercept him. If he takes off again, who cares? You don't need to chase him. Now you've got his plate number and a detailed description. If his plate number turns out to be fake or whatever else, now you're building the case against him for if and when he eventually gets caught. It all can add up, is what I'm saying. Yes, it may end up being wasted effort if he's constantly switching bikes and constantly moving around, but it's really not much effort when you get right down to it. And it may end up paying off.
