A ban for 90MPH in a 70? wow that is harsh!
I was under the impression that it would be a fine and/or points.
I often travel between Portsmouth and Kent but dues to ferry prices from the Isle of Wight, we travel during the night when the ferry is much cheaper.
Its very frustrating doing 60-70 on an empty motorway. It feels like your going much much slower and it is very tempting to speed up, especially when you get the odd person sip past doing probably more than 100.
Just not worth the risk IMO. You never know who is watching and more importantly, what is around the next bend.
I was doing 70 round the M25 in my old Volvo at about 3AM and the road was empty, we were just coming past the Crawley/Brighton turn off and noticed an ambulance in the hard shoulder with its blue lights on, we both turned and looked to see what was happening and when i turned to look ahead again, there was a heavily smashed up, unlit wreck sitting in the fast lane. I swerved and just clipped it.
So yeah, whatever the situation, Don't exceed the limit and keep your eyes firmly on the road.
