dispute it, go to these traffic court a few times to rehearse yourself,
know when is your time to ask questions. That is very important, once u passed that time u can never ask again while in court.
raise doubt, was the traffic heavy, ask why he didnt elect to pull you over right away?
All he need is to turn on the light bar and make a U turn.
Waited 3-4 mins thats a long time, is there a concrete divider?
sometimes they may not attend becoz his evidence is thin too.
Can your car possibly go 106 km? and the part of hwy there safe enuf to go that fast?
is your record pretty bad?

how generic is your car?  IE  Acura, Honda, Toyos
at any given time you can see 2-3 on the road can even be same color.
Tell the court there were at least more than two on the road.
What time when it happened, dark too?
When a swarm of cars heading your way is much harder to tell which is faster or slower.
Also say there is a 51% greater probability that you're not the car in question.
The Police have to prove that you're beyond reasonable doubt in going at the allege speed..
Go ask for some help from Law students, try to  read some court transcript, learn how lawyer say things.

Finally the info on the ticket is it all correct,  the address to area of conviction. Any part of not Kosher will be thrown out.
So read the ticket description thoroughly.

Deduct the time, so the site offence may not be the place where he pulled u over.

Were u driving on the fast or slow lane.
Have a diary of all happening now, before memory fades.

Are your tires good? if not just point out is impossible to go that fast at all.
