Hello,
I was driving down the "Limehouse Link Tunnel nr Hertsmere Rd W/B E14" and got flashed at the entrance, although the speed was slightly over 30mph (31maybe) Recorded speed on NIP 35mph, so I was slightly confused, upon taking a closer look the speedometer needle seems to be way below 0, my service is due in 20days, I keep up-to date with yearly check ups.
Any advice please?
