Well, i cant see what the fuss is about ??
I had them on the 2022 Rallye loaner i had over Christmas & new year
Quite a lot of other bike riders commented on how bright the set up was, and I could be seen for some considerable distance
They did comment on the fact that the indicators do get a bit washed out,
but if you ride behind many modern cars , Range Rover being one, they have a similar set up, and there still going
Its pretty easy to work out
Indicators = indicators = there is an intent to turn or a signal to other road users
Brake lights = Braking activity is taking place
Brake light's & indicators = Braking activity is taking place & there is an intent to turn or signal other road users
If your still accelerating or not slowing or preparing to slow to something showing brake lights, then a flashing indicator would make sod all difference. ?
Ssssh, common sense and rational argument is pointless to the few that have made a decision on this. Even if your riding is piss poor and you indicate only when you're started braking, as you say the scenario is still braking! How does this change the reaction of the car or biker behind? The only scenario I've had explained to me is the case where a motorcyclist is slowing down and indicating, and another rider has approached with intention of overtaking a braking vehicle? As you say, it's the same set up with cars, and personally if I were approaching a car or motorcyclist that's braking I wouldn't be thinking of overtaking (unless there was a clear reason why the vehicle ahead was braking), but I guess it's a potential scenario.
Similarly, the front lights - Hondas have used them for years without any evidenced issues (including my own Honda experience). Very few of us will have NOT experienced a car pulling out on us - we bring our experience to anticipate these and to defend against them. (Funny how near incidents get less the more years you ride a bike!). But all of a sudden it's due to BMW having adopted amber indicator drls!
Some profile modding bloggers and salespeople are fuelling thing, whereas I bet Motorrad central are bemused by it all!
