When lawnmowers use GPS coordinates to operate while I'm on a ride or doing just about anything else, I'll probably buy one. The remote is cool, but if I gotta be there watching it what am I really gaining? Kinda like no-steers in tractors. Of course there is the safety factor. Lot's of super duper duty forklifts are using remote technology to keep operators off the machine in case of a tip over. Pretty cool.
If you're gonna be dumb, you better be tough.
