You can hear when the car is on the limiter from on board cameras. As well as the shift lights, the driver can hear it. Nowadays, the cars are geared to be close to the limiter in 7th, with DRS activated. The Red Bulls, and Mc Larens in particular, can be heard banging the limiter on straights. Re watch on board with Hamilton trying to pass Schumi at Monza last year....
Brian, I watched the video, and the revs to rise after the chatter, albeit the point between chatter and the shift point is close when revs rise that quickly! Remember the shift light activates 1500-2000 rpm lower than the limiter in 1st and 2nd gear to allow driver reaction time. The shift light stays the same if he revs the engine higher. At the first point of chatter you will see only the left part of the lights illuminate. Remember that we don't know what the lights are set to show in the starting phase, and the cars have multiple modes on the steering wheels.
Re watch it, but don't be fixated on the shift lights, and listen carefully. You have to 'feel' it....
Odd that... i'll just add another 500rpm to my redline tonight by adjusting the fuel cut in ECU
Not every engine works like that. Most i've known use a combination of fuel cut followed by ignition cut... soft limit to hard limit, some one or the other
But f1 cars im sure use some awesom tricks so their rev limit isn't as harsh as my firespitting overbored 1080cc v-twin motorbike that sounds like its shitting out valves when you bounce it on the limiter like a loon
