And the results are in:
excessive speeding: $368-483, 3pts - stuck, but minimum fine of $368
drive without due care: $368, 6pts - dropped!
...Interesting to note, this came after talking with the same officer who originally told me, "If I dared to dispute this, [that he] would walk over in front of the judge and up the fines to the maximum, and add in a street-racing charge to boot!"
Guess it was worth it to call that bluff
