I foresee an uptick in trompe l’oeil artwork of stairways, “speed bumps”, open doorways, fountains, strollers, entire landscapes etc to fake out and confuse auto-bots.
Should be massive fun.
Strategically placed mirrors should be hysterical also and anechoic material for those that use ultrasonic range-finding.
Then there’s graffiti tagging. Going to be amusing.
