This definitely doesn't happen on my 2012, if it can be enabled my mind will be blown also! |

I was very suprised. My route into work (south from Watford into London) doesn’t have any gantrys so I’ve never noticed it before and I don’t generally use cruise control. Noisy black one |

They dont as far as i am aware it only slows when it sees something in front if you have the radar system and when clear it speeds back to the original set speed |

On a similar note.

I assume it does put brake lights on as the active cruise really brakes hard if you get to close to a car in front |

More likely a bad driver with an expensive annual brake bill. Adaptive cruise systems rely more engine braking / air resistance than constantly dabbing the brakes to stay within the distance window set by the driver. L405 P400e Autobiography (MY2020)... Silicon Silver / Espresso RRS TDV6 HSE Lux (MY2011)... Nara Bronze / Arabica - now gone! |

I love the adaptive cruise control, but it does occasionally slow down “accidentally” when detecting a car in another lane, especially if there’s a bend and the car is actually a lorry. The active cruise control scores rather poorly on the driving statistics compared to a human driver. RRS MY17 SDV6 AB

I quite like mine, I had a wagon swerve into my lane to miss a car that pulled out in front of him and the sport halved its speed in a milli second. Shocked me a bit at how quick it reacted. I also have the collision warning turned on and although it’s a little annoying at times it has alerted me on a couple of occasions when I’ve not been paying attention. 2019 5.0 SC SVA (Current)

My one gripe about it that it takes far too long getting back up to speed. Steve. |

If the system applies the brakes then yes, the brake lights are illuminated. Which is a good thing as it means the following driver knows the vehicle is braking. 2012 SDV6 - it's missing a couple of cylinders 2008 TDV8 - it was a labour of love and is much missed |

yeah but it didn't appear to slow down significantly.
