In order to be most effective it would need to be dynamic rather than a fixed on/off like rear brake lights. Stopping doesn’t mean stopped. So perhaps a progressive light bar that starts lighting up at 20mph and adds a light for each 5mph drop until the whole bar is lit indicating a full stop. That would give pedestrians a sense of rate of deceleration.
They can get you for destruction of property then. Luckily most non-law enforcement use cheap ass boots. I had an apartment complex boot an old truck of mine because I let the registration expire on since I was about to trade it in for a new(er) car. I simply deflated the tire enough to wiggle it free and threw it in a bush, then I pumped the tire back up and drove it to a Walmart parking lot for a couple of days.
