We visited a forest we’d never been to before to walk the dog. The main car park lay at the end of a road and we kept driving, ignoring the pockets of parked vehicles along the way, until we reached a sign that said that beyond this parking must be paid for - pay and display.
As we were unfamiliar with the routes around the forest, we were happy to pay the price for official reassurance. Now that we’ve been once, in future we’d park at one of the free stops along the way.
As soon as you tease your audience with a workaround that requires less effort, time and cost, you should expect they will take it.
