GTE speed limiter

[gucom]

If I remember correctly, the ACO press release regarding the end of GT1, and the transition from GT2 to GT Endurance, said that power figures would be allowed to rise, with top speeds capped in other ways.

I've seen several people on ten-tenths mention a speed limiter being the method of choice to cap top speeds. I didn't read about this in any ACO release, but maybe I missed it. Is the speed limiter confirmed by the ACO?

If so, first of all the idea of a speed limiter on a racecar seems kinda ridiculous.

Secondly, how are they gonna implement it? If they set the speed limiter at, say, 290kph, it'll only be effective at Le Mans since the cars don't reach similar speeds elsewhere. If they set the limiter at 260kph, that'd create huge speed differences at Le Mans. If they vary the speed limiter for each circuit, what would they base it on?

To me it seems like a very bad and contrived idea... or can someone show me the logic in all of this?
