I don't know about a 4 wheel scooter like that. At 12 miles per hour, a hard or panic stop on a down grade means a face plant. At 20 miles per hour, it means a face skid. It seems like you might find out just how long a skid mark you can make with your nose...
It is an upgrade to the typical Q platform, but the basic physics of that high a center of balance being stopped by a restriction on the wheels, means the weight is moving forward if you like it or not.

That all seems to be true of their device -- note the bicycle hand-brake control.
But it's not quite inherent in having 4 wheels. Segway balance control isn't quite precluded by having more than two wheels.
We could, for example, tie you to a pole, and maneuver an 8-wheel steerable device to remain beneath you, based on deviation of the pole from the local-frame vertical.
You're still going to need all the same sensors to determine local-frame vertical.
