How are fines issued?

A fine can be issued if a user is breaking the following parking rules:

• ending a trip in an out-of-bounds zone
• parking in a forbidden area

Costs of parking fines for a specific region can be obtained from the price list for that region:

{
  "name": "regions/aAbBcCdDeEfFgGhHiIjJ/price_list_details",
  "scooter": {
    "endTripOutOfBounds": {
      "amount": 100,
      "currency": "EUR",
      "unit": "UNIT_TYPE_EVENT"
    },
    "endTripParkingForbidden": {
      "amount": 200,
      "currency": "EUR",
      "unit": "UNIT_TYPE_EVENT"
    },
    "ride": {
      "amount": 0.4166666666666667,
      "currency": "EUR",
      "unit": "UNIT_TYPE_SECONDS"
    },
    "startRide": {
      "amount": 300,
      "currency": "EUR",
      "unit": "UNIT_TYPE_EVENT"
    }
  },
  "bicycle": {
    "endTripOutOfBounds": {
      "amount": 150,
      "currency": "EUR",
      "unit": "UNIT_TYPE_EVENT"
    },
    "endTripParkingForbidden": {
      "amount": 300,
      "currency": "EUR",
      "unit": "UNIT_TYPE_EVENT"
    },
    "ride": {
      "amount": 0.4166666666666667,
      "currency": "EUR",
      "unit": "UNIT_TYPE_SECONDS"
    },
    "startRide": {
      "amount": 100,
      "currency": "EUR",
      "unit": "UNIT_TYPE_EVENT"
    }
  }
}

If a user has incurred a parking fine it's reflected in a trip invoice:
