There is no such thing as an automatic ban. there are speeds at which it will 'automatically' go to court, but not necessarily a ban.
And at the risk of sounding negative, you could still get done for speeding if he had you on video.
A few years ago a got caught overtaking an un marked car doing over 90 in a 60. The copper pulled me over, showed me the video and basically agreed I wasn't riding dangerously but told me to slow down and then send me on my way. A few weeks later a get a letter throught the post telling me that they have since reviewed the days footage from that car and they are going to prosecute. Went to court and got 3pts and £350 fine.
I thought this took the **** abit especially as the video showed the unmarked car doing 80 before I overtook it. So if they were going to do me they should do him as well.
Sorry I realise this has turned into a monday morning rant
Any way I hope you don't have the same experience.
