Why not? If the ISP provides a server you can download a file from, you can see your speed, the ISP can see the speed. Yes there might be issues with your PC and such, but this can be easily tested.

That would be stressing the system. My point is as a consumer, you can't continuously measure your maximum bandwidth without using it all.

  Well you always have Layer 1/2 data. DSL modems, cable, LTE ... will show diagnostic information on which you can estimate some bandwidth, more or less.

    That doesn't help you figure out if there's congestion two hops away in the ISPs network due to them oversubscribing their backhaul links.

      True. That's what speedtests are for. Ideally you have your own server, so that you can factor out at least one third party.
