Other posters have pointed out that, as they're so cheap and widely available, Robinsons are so widely used, and often by relatively lower-hours pilots.
I don't know much about helicopters but I do know lots about statistics...and that's why a Lamborghini or Ferrari is unlikely to kill an 18-year old male driver - it might be powerful and tricky to drive, but most young men will simply never get near one. Check the grisly roll call of Citroen and Peugeot hatchbacks - they're not dangerous, just lots of them on the roads. Same with aircraft.
I'd chill about the Robinsons and panic about the millions of sometimes incompetent, poorly trained and almost entirely unregulated idiots driving within feet of you every day. After all, it'll be a while before PPL(H) holders kill / injure 3000 people in the UK every year....
