I always have trouble understanding why people are so keen to shut down discussion.

It's not about shutting down discussion, it's about trying to moderate the discussion so it doesn't veer off into some flight of fantasy and vivid imagination.
To address some of the concerns, misconceptions and assumptions expressed in this thread here are some answers.

Equip flag marshals with radios? Is there a circuit where there is not a radio available to either the PC or I/O on any post.

It only works on circuits where there are light panels. Incorrect. Code 60 works perfectly well when instigated by radio rather than RC operated light boards. Something the MSA will HAVE to address as progression round the circuit visually will not produce the fairness of no disadvantage to drivers that simultaneous flag display gives.

As a marshal you can only report the facts. Unfortunately you can never accurately say how fast a driver is going at a given point There is absolutely no need for any marshal to estimate, report, comment on a competitors speed it is controlled by the timekeepers and sanctions are levied from the timekeepers records.

It was called the Battenberg FlagThe Battenburg was vastly inferior to the Code 60 as competitors never knew when the green was going to be shown at the start/finish line, resulting in the cavalry charge at the end of each lap. With the Code 60 everyone starts racing simultaneously.

on circuits which don't have the technological advantages of unlimited wealth - I too think will be difficult.This is where the feedback to the MSA on their proposed regulation is essential.

when safety cars were rare beasts and drivers abided by the spirit of yellow flags.The point of the Code 60 is that the whole circuit is made safe and although marshals can deal with whatever incident instigated the 60 all posts can attend to husbandry/debris/oil in their sector at the same time knowing that no-one is a loose cannon trying to catch up with the pack.

the MSA (or applicable ASN) actively enforces the existing yellow and double yellow flags, by doing the same harsh punishment and re-set the acceptable standard?From the Hankook 24 hr series regs regarding overtaking under Code 60.On decision of The Race Director this can be penalized with a time penalty of 1minute!... Sanctions applied to speeding under Code 60. Any car that exceeds the speed limit of 60km/hour can be sanctioned, with a time penalty of at least 10 seconds. The Race Director can increase this time penalty with the double value of the encountered advantage when driving too fast. At Dubai for each and subsequent speeding infringement under Code 60 the teams previous penalty was doubled, then doubled again.... repeat offenders learn a very hard lesson very quickly and soon find a way to do 60kph.

If they policed the yellow flag rules strictly enough, there's no need for another set of rules.As I said above this procedure is about the entire safety of the whole circuit so all marshals can go trackside briefly during the Code 60 not just enforcing a reduction of speed in a particular sector nor about destroying the rhythm of the race

How do you "judge" that a car is travelling at 60KPH? Human perception of speed is both subjective and relative. When reporting we can only state facts, not guesses, estimates, or guesstimates.We have nothing to do with the judging/reporting of speed it is calculated electronically by the timekeepers and therefore guesses, estimates and guesstimates don't come into play.

But they can only do that over a lap, circuits like Mallory don't have Sector timing, and no where has it between Flag Points.This is a problem the MSA will have to address and hence feedback to their proposal is essential.
