That's because group cyclist are aware and take precautions ahead of time. A brake light would lessen the need for that distraction.
It appears that you are equating <being aware and taking precautions> with <distraction>.
Maybe that's not what you meant?
In any case, cyclists need to be aware and take precautions at all times. The same should be true of everyone on the roads.
Perhaps you meant that a brake light would reduce the work load for cyclists? That might be true, but as I mentioned earlier, I don't see a problem with cyclists rear-ending each other. Maybe I'm just not riding where the problem exists.
In any case, Cateye seems to think that a market exists, since they are making that Rapid X light that senses deceleration.
Interestingly, there was a kickstarter project called "LucidBrake" that did the same thing. This was in 2015.
There is a more basic type of brake light from Sigma....

I've actually seen a person using one of these. it was invisible in daylight.
There's a more generic and cheap version of this same idea.....

and there's some sort of DIY brake light on Instructables

There's no shortage of bike brake lights that are available. Maybe someone needs to invent a need for them? This is more of a marketing challenge than an engineering challenge.
