Emails of a few lines used to do the job, now it’s a couple of pages of html most of which is advertising!

Yes online marketing of any kind can be frustrating at times but lets be honest it isn't really causing speed issues for your setup is it?

"Car manufacturers publish figures and they have similar wide variables, but manage to constrain them to @56mph, for example."

And these figures are not based on real driving. No wind resistance so of no use in the real world. Bit like theoretical Wi - Fi speeds.

In the real world two Ford Fiestas (for exaple) driven by same person will have slightly different figures from each other.

At least the figures are published. If you tie them down enough they wil have some relevence: if only against each other.

And the WiFi numbers are calculated and scientifically determined, for example if you have a WiFi 4 (N) device with single antenna it does 72 Mbps, and if you have two antennas it is 72+72 = 144 Mbps. That has no real relationship with throughput on fixed Ethernet however.

Compare the WiFi 4/N 144 against a WiFi 6 1200 or 1400 and you can see the relative improvement. You can’t compare WiFi 6 1200 with Ethernet 1000.

Car efficiency figures may be published but are of no use as they do their best to shown the most efficient value they can achieve.

Bears no resemblance to real world figures.

Some PHEV show figures of over 300 mpg. Funny that! Then when the battery has run down the fuel consumption is worse than a non PHEV and more pollutants out of the tail pipe.

The research group Emissions Analytics found that, and others, which along with the DieselGate stuff, caused the likes of EU to change the method they test cars... still not sure its great.

The analogy with WiFi is that the published number is only comparable to another published number, not to actual throughput achieved. UNLIKE with Ethernet where 1000 Mbit/s ethernet will give 940 Mbit/s throughput on a TCP/IP connection.
