Periodic reminder:
Any and all use fees for government services are a regressive tax on the poor. This includes things like road tolls, car registration, fines, car inspections, on and on and on.
Anytime it's the same price for everyone, it's a major part of the income of someone in poverty, or even driving them deeper into debt, and negligible pocket change for someone wealthy.
Even allowing for someone to fill out paperwork for a fee waver means that they're having to pay the fee in one of the most scarce resources of someone in poverty - time and energy. Just make the damn things free and pay for them with progressive income and wealth taxes.
