#3onewheels suffer from a problem known as nosediving in which the board shuts off when it can't supply enough power to support the rider, as the board is self balancing this is a problem intrinsic to the board's form factor. The board works in a similar fashion to balancing something like an umbrella on your hand, as the rider leans forward it creates an imbalance that requires the board to accelerate in order to keep the rider upright. The only possible safety feature to prevent nosedives is to inform the rider that they're approaching the board's limits, this is done with "pushback" where the board elevates the nose making the rider uncomfortable, signaling that they should slow down. Newer boards are more aggressive with pushback, it's definitely a balancing act giving the user the most power from their board while also preventing them from nosediving, future motion faced significant backlash when their new flagship board implemented extremely strong pushback at a speed lower than a prior discontinued model

Seems uncalled for.

Good summary. I would just add that "can't supply enough power" is a state the board can enter into either in lower battery levels or (more often) when a rider has put their center of mass too far forward, causing the board to work harder to stay under them, while also moving at a higher rate of speed or accelerating - the board can't give enough power to maintain this.
Pushback is to be respected, but the user can also ignore it and carry on. It's literally the board telling you that you need to get ready to run if you don't stop, but many will just ignore and keep on keepin' on, often at speeds faster than they are capable of running.

I've said before that Onewheels are the Lawn Darts of our generation, we're lucky to enjoy them before the nannies start taking our toys away. They are super fun though - so much fun.

#8With thunderstorms, you count seconds 'twixt bolt and boom.
With the current golden age of electrified last-mile transport, we're seeing the gap between innovation and regulation opening up wide -- now several years.
Real-world impact: I routinely get up to speeds on my e-bike that are, quite simply, dangerous. It's not that I never hit 25 miles an hour on my old road bike, it's that I spend so much more time hanging out at ~25mph on my ebike that potholes have gone from annoyance to mortal danger.
The risk is somewhat mitigated by the enormous tires and superior build quality on the braking system, but not entirely. I'm glad to have taken a motorcycle license training course, and heartily recommend that other early adopters think about voluntarily seeking out additional training (and I imagine e-* specific courses are available now, if not soon.) Not all good ideas come with mandates :D

#9Do segways have a similar problem or is the vehicle large enough that it can always counter balance your weight?

When I was a teenager I rode my skateboard down a parking lot ramp when I realized I was going way too fast, was about to enter the street and the only way to bail was to jump off and run. It looked about like that video.
I didn’t realize these one wheels have top speeds of 16-20 mph. That’s faster than most people can sprint. 16 mph is a 3:45 mile. 20 is a 3:00 mile.

But I dunno, where do you draw the line? As a 50 year-old who makes a living typing I chose not to buy a table saw last year because I decided it was inherently a riskier tool that I ever wanted to use. I ended up with a track saw instead. I think that was a good decision but not sure it’s one I would have been wise enough to make in my younger years. Now I’m not advocating for banning table saws: my point is that Onewheel can put every warning and disclaimer in the world on their product and some people will still not appreciate the risks involved.
That said, 4 deaths over 2 years doesn’t seem out of line with other products in the same category. I wonder if something else is going on to draw the CPSC’s ire.
