Wait, isn't America meant to be land of the free? Is it their front lawn, or is it not? I live in a much less "free" country according to any American, and yet neither thing would be a problem. It's your front lawn, want to a park a car there? That's your call.
What an incredibly weird argument that is.
You get it! And for me and most other people who live in cities or towns, parking a vehicle on your front lawn or other area not designed for and built for parking a vehicle (most people call them "driveways") is crossing that line.
