This becomes a thing and I'll have a 25mph sign hanging off the back of my truck. I eagerly await starting a youtube channel of new cars losing their shit on jammed tailgating attempts.

Or in Germany, if you live in the village, put up a 60 sign by your driveway and when confronted just say someone is having their 60th birthday… Germans for whatever reason like putting up a speed limit signs by their driveway when celebrating birthdays.
