$75 is not enough to pay a lawyer for 1 hour to prove the company’s right to collect $75, and they have to file a new suit for each person who didn’t pay. Not to mention there is a chance of losing and having to pay legal fees for both parties after years fighting in court. It’s far more profitable for them to pocket the money from those who do pay and forget about the rest.
In my case, the tickets I get are usually $150 to $350 per and there isn’t a single instance of someone being sued for non-payment.
They tack that $75 on per unpaid toll. So you drive the length of the tollway and pick up 9 of them, that's 9x$75 or $675. Then you drive back in the evening. Do that for a couple weeks before the mail arrives.
