Not sure if other states have many of those speed detection gantry's that display speeds of cars travelling in each lane on major highways.

I enquired about them in Victoria, hoping to find some closer to home, but unfortunately they're either a fair distance away, or are being decommissioned.

Reason I ask is I want to find out the MK7 GTI (MY16 manual, just to match my car, if possible) actual speeds are, when the digital speedo is set to 100, 80, 60 & 40km/h.

Haven't been able to work this out as yet, which is frustrating because in my local area, when doing 60km/h, many cars speed past (many of whom are hoons though), so i'm left thinking VW may've been extra cautious with reducing the actual speed as compared to the speedo reading.

Can someone with as similar car to mine, & with the digital speedo confirm what the actual speeds are at 100, 80, 60 & 40km/h? I'd really appreciate it.
