Auto-lawmowers tire me out with the need to control a sledgehammer urge. The size must trigger some primordial instincts or something. And they seem to distract from decent, living, social solutions like in Curitiba, Brazil:

This solution would contribute to Resilience too. After a earthquake (any grid-disruption) we could eat sheep, or be intense gardeners with manure. @strypey
