Yes, it does - 1980.
First up, my question/comment is the same whether 'net neutrality' - or this decision to end it - is ultimately a good thing or a bad thing. What I am chiefly referring to is the outright, provable lies about broadband speeds and investments told by Pai and repeated even after this was shown to be incorrect.
As I said in a previous post: whatever the ultimate benefits or downsides of reversing the net neutrality ruling, it is clear that Pai's professed reasons for doing so are not the actual reasons.
But second, you analogy just doesn't work.
On a road, the main reason to charge more for, e.g. a truck is that a truck, by it's physical nature, degrades the road more and thus requires more maintenance. That's why many toll roads charge less for a motorbike than a car - less wear on the road. A truck also takes up more space than a bike.
What you should understand is that NOTHING in net neutrality prevents ISPs from charging based on the volume of data downloaded/uploaded by a subscriber, which is the equivalent, in your analogy, of the number of axles. Or, perhaps, more simply, the weight of the vehicle.
The point of net neutrality is not to say that you can't charge more for a truck than you can for a car (i.e charge by the number of wheels/packets) but that you can't charge more per wheel or per unit of weight when the truck belongs to company X or is carrying company Y's widgets in the trailer. You don't get to set a lower speed limit, either.
THAT is what net neutrality is about.
It says that, if your network is transporting 100Mb of data, you can't treat that 100Mb any differently than any other 100Mb of data - it doesn't matter whose truck it is, what depot it came out of, what it is hauling or who the end recipient is - 100Mb is 100Mb and you don't get to prioritise company A's cargo of frozen corn over Company B's cargo of toasters.
You can charge by weight (total data transmitted) but you can't charge two amounts for the same weight. You can, I believe, have peak and off peak rates but, again, you can't go charging more or less (or allowing higher or lower speeds) based on the specific cargo.
Slowing the whole road down (rate limiting) is also okay but, again, you can't just slow down all the traffic from one supplier while allowing the another supplier to go at full speed, nor can you apply a 'peak' charge to one but not another.
You can't, in other words, slow down (rate-limit) all the lanes except one but then charge a premium surcharge for traffic on this new, miraculous, 'fast lane'.
(Sorry for any typos - have to dash.)
