Some companies in the Bay had them for getting around campus and eventually got rid of them because of too many incidents, so the helmet and small bumps thing was probably for the best. I rode one and it seriously goes faster than I'd be comfortable ditching it. It's also very possible to fling yourself off, tip over, etc. I'm not generally comfortable with a transportation device until I find the limits (so I know where they are), but it was scarier than it should have been. You have to basically trust it not to slam your head into the pavement, but I guess I've just been around dodgy electronics long enough to not be so naive. Then again, now we have electric longboards, which are like an order of magnitude more dangerous. At least with the longboard, you still have 4 wheels if all the electronics give out. Then again, some of the DIY stuff out there...I would not trust my life to a rPi descending a hill in SF with traffic. The foot brake always works.
