Can we get back to the point guys, referring to the PAL-V. In my opinion, this particular 3 wheeled vehicle is safer than a motor bike on the road. Unlike the old and dangerous types with one wheel at the front, this one leans into corners so is not so prone to rolling over. I doubt that anyone who can afford one, is going to be so stupid as to try racing it through the hills. As for crumple zones, not needed as it's 'experimental' and besides, if you can legally drive one of the Lotus 7 Clubman Sports, then your in the same class of vehicle(re safety)
As for Jesus Nuts etc, this is as safe as any rotary wing aircraft and probably more so than a helicopter. It's proven to fly safely and is still being evaluated and up-graded.
As for cost, yes, a rich mans 'toy' but I'd have no problem buying and flying one if I could afford to do so.
