Can G05 drive dynamically by speed limits?
Hi, I know that G05 detects signs and suggests speed limits based on streets signs and GPS data. But does G05 also have an option to drive dynamically by speed limits, that is, when adaptive cruise control is active? For example, I set 90kmh limit on cruise control, and when detected speed limit is for example 60kmh, vehicle would slow down to 60kmh?

Not in the US, but I much prefer BMW's system to Audi's (as in my 2018 Q7). Here's why:
In the Audi, if you had automatic speed control set, it changed the speed automatically based on speed limit signs. For example, it automatically lowered your speed to 25 mph (or even 15 mph) in a school zone, even if the school zone was inactive (i.e., not during school hours or on weekends). Immediately. Even with moving traffic behind you. Which was not amused by you suddenly reducing speed more than 30 mph lower than the posted limit. Or driving on the Interstate, it would read the posted limit and adjust speed accordingly. Including the access road sign parallel to the Interstate, which was 40 mph slower than the actual posted Interstate speed. Sometimes with - really fast - moving traffic behind you. Which was not amused by you suddenly reducing speed more than 40 mph lower than the posted limit. Or the posted truck speed, not applicable to you, also lower than the posted limit for cars. Because, you see, it couldn't tell the difference. Or the hand-lettered sign in the construction zone, which you could read as 30 mph. Which the Audi, however read as 80 mph. Very exciting. In the BMW, it simply pops up a speed limit sign in the HUD and allows you to select it. Or not. Without the drama. I prefer, let's see, BMW. Without having to think too much about it. |

Here in the UK it does adjust the speed limit for adaptive cruise control. sometimes it works well and other times not so much. As has been mentioned it’s high risk when it spots a much lower limit and adjusts immediately when you’re cruising along at 80mph.
Mine has read speed limits in car parks I’ve passed at 10 mph and adjusted and here in the UK lots of urban areas have 20mph limits with signs at the turn in to the respective road. Mine is forever picking them up and slowing me from 50, 40 or 30 mph very abruptly. Also a new source of irritation last week was 60mph roads in Scotland with a 40mph for trucks. Guess what mine decided to do every time it saw a 40mph for trucks sign, hmmm |

I would add to the above mentioned fails of signs detection the fact that it may read exit from residential area as common road or crossroad and cancel the speed limit that was set previously.
Also the system doesn't see correctly the speed limit upon some conditions - weather, type of transport, specific lane on a highway where there could be a slower speed limit. These all issues affect the signs detection reliability, which I think is no more than 50%. I never used aSLA, because of that, it can be dangerous or lead to multiple fines for overspeed. Overall, IMO driving assistant works nice as traffic jam assistant or on a highway that you know well. |

I have a polarising experience in the UK. It works 95% of the time and I hardly ever set the cruise speed anymore. So relaxing!
Very occasionally spots a discarded temporary road works speed limit sign that workmen leave behind, but other than that it's nailed on. Not known any weather dependency with aSLA. Distance control yes, but not aSLA which makes sense as it uses NAV data when road sign info is not available. Maybe the Honda Civic behaves differently |

It’s one of the first features that I searched for and turned on in my car but also one of the first I had to turn off again.
Works rather nice on smaller roads but when doing 120km/h on the highway the camera’s sometimes spot lower speed limit signs on an exit or a parallel road The adjustment to the lower speed limit that follows is dangerous at highway speeds as no one driving around you expects it. Maybe the cars intelligent systems will be improved to avoid this in the future. I’ll keep trying it as software updates roll in but for now ... I keep it disabled. |

The traffic light stop/restart feature is not available on any Bmw or even Tesla model yet. The coding is there for the g05, but not active in firmware. Have you coded the car? |

Did it stop at traffic light by itself or was there a car ahead of you?

Setting up a centralised infrastructure will be too expensive and not every city may go with it. |

It's quite a bit out of my way but I'll film it next time I'm in the neighborhood. In my opinion the ACC is the best I've seen in any car.. |
