Will investigate this as a potential Insim bug, as far as I was aware, that part of the road is 135KPH and not MPH even though it says it on your screenshot.

Refund Request Approved
The refund transaction will be processed and we will notify you when completed.
Since this is a bug and not necessarily your fault, nor the cop's, we don't really want to fine the cop, so I'll just give you the fine of 80 InSim Euro myself. It is a very small amount of money and not really worth wasting any time over in the first place.
As a side-note, you'll be banned from the server for a horrible attitude/swearing etc.
Refund Processed
