Got caught down the M1 at 110.5 for a 5 miles back in 1996. Think it was between J12 and J11 southbound at 1 am.
Copper was fine, suggested I goto court and give evidence myself and present any mitigating circumstances i.e. job etc.
I also employed a barrister - oh how posh.
Well I ended up standing in front of the Hemel Hempstead migistrates and gave evidence telling them what a bad lad I had been and how I had let everyone doen etc etc.
Ended up with a £400 fine (I was an IT contractor then and was means tested) and a £200 barristers bill. Oh and a 2 week ban with no points.
This didn't end up costing me anymore money on insurance and taught me a VERY valuable lesson about speeding. Not least of all because of the inconvenience of public transport living in Hull and working in London ! In fact I have driven much more steadily and cautiously since but of course have my moments and still enjoy my sports cars more than ever
Good luck.
