The chances of your ticket being withdrawn are about 5-10%. That will only happen if the officer does not attend court and the JP is unwilling to adjourn the matter to another date. Remember, limitation periods have been frozen for all POA court proceedings so the 18 month Jordan time frame that normally applies is not currently applicable. While there will be a bit of a backlog at first, the government/courts will pass rules that give the system time to catch up without penalty.
Still, given the current uncertain times, you can simply plead not guilty and see how things progress over time. By doing so, you preserve your rights and you can pay your ticket at any time before your trial if it looks like it will indeed be going to trial. Of course, if you DO decide to actually go to trial, they will undoubtedly amend the rate of speed back up to 86 in a 50 zone (36 over). That's called a Winlow amendment. In your case, the officer used a LIDAR (laser device) which is quite accurate and more difficult to dispute since they usually make sure the laser beam hits off your car's licence plate or front grill.
