The proliferation of giant screens around the circuit has reduced the need to listen RLM anyway.
Sort of true, if people are out of sight of a giant screen, i.e. in a campsite or travelling near the circuit, then RLM comes into its own as always!
We still have our small 1 ear RLM radios from last year, easy to carry and use, and usable else where too (as we found out at Spa) . Ok, the sound isn't the best quality but they do the job!
