The blade brake on a walk behind was mandated in 1982 at a federal level by the CPSC. Riding mowers were mandated by ansi 2003 standard, including everyone's favourite 'operator presence control's aka the seat safety switch. Most everything safety can be disabled if you really want, but anyone pontificating about CA compliant emissions on small power equipment can go sit with the coal-rollers as far as im concerned. Edit: to stay on topic, if people start getting frequently maimed by drones then I'd expect to see some crazy CPSC action like an altitude safety switch or something...
