NSW when is it harrasment

I appreciate that police and RBT units are an effective tool used by police to prevent accidents and save lives.
I live in a small town with around 1000 residents near the beach. There are 2 ways into my town and of course 2 ways out.
The police quiet frequently use the main road as an RBT stop at least 2 times a month and sometimes 2 x a week.
At first I thought it was a good thing that this was happening and looked after my local area keeping drunk drivers off the road and helping keep my area safe.
HOWEVER. I started being pulled over continuously on my way home from work , This year alone I have been pulled over and random breath tested at least 5 times already.
It started getting annoying after i had lost a P plate on my way to work and on the way home was fined a large amount of money and lost demerit points. I was pulled over again 2 weeks later in the same place where i was then fined $448 and will lose 3 demerit points minimum for obscure number plate with P plate for my P plate slightly covering the last letter on my number plate after it was tied on to try and stop it from coming off and being fines and possibly losing my license. 8 days later I was pulled over again and could not find my license at 1st and was threatened with more fines but then found my license down beside my seat.
I wish to take my case to court to ask for leniency and a chance to keep my license.
What I would like to know is can I get all the information from police on their stops in this location.
EG;
How many times this year and last year have the police set up RBT in this location
How many actual drink drivers are actually caught here to prove why it is needed so often
How many OTHER fines are given out in this location

I would also like to know if this becomes harassment after being continuously pulled over at the end of my street simply trying to travel home from work in normal daylight hours.
I have never seen the police in the position at night time or early hours of the morning when a large percentage of drink drivers are usually on the roads.
These set ups are usually around midday to 2pm

Im starting to feel harassed by our local police in my small home town.

So my main Q's are.
1 Can I get the information I seek from police or any other place. ?
2 Can this be deemed harassment ?

but are you even still within time to court-elect the infringements?
Yes I have applied for leniency 1st via online and awaiting a reply. it said last i checked wait for up to 42 days.

Looked at from another perspective, which could very well happen if you put yourself before a magistrate: why did you persist in driving a 'defective' car through a known RBT hotspot if you have any sort of expectation this would end differently?

It wasnt noticed that the letter was slightly covered. Hence we never thought there was a defect.
I respect that I have made a mistake.
But it is a small one and 448 and 3 points is over the top.
I;m happy to pay the fine to acknowledge I have made a mistake .
The number plate was not covered to hide anything else like someone might to hide that the car is not registered or to commit a crime maybe. and being in my work clothes and my address on my license showing i live just a couple of hundred meters down the road it is easy to see that there was no malice intended.
I own a small cafe and work usually 7 days per week. I employ 7 staff members including my brother who I also drive to work 4 days per week.
Sir I ask for the court to take the god damn revenue and gimme my damn license back ! Ok would not finish like that.. but how would my argument stand in court ?

Ok all thanks heaps.. good to hear the legal side of things..
Cheers
