Even bigger, fatter wheels might help, like car tires or some e-bikes.
But honestly if we are blue sky dreaming for a second - I wonder if there will come a time when a two wheel kick scooter can self-balance, such as by using more wheels in a different configuration or by using some other kind of board or motor technology to stay balanced more of the time. If a scooter also had the ability to predict if it was going to crash into a curb or pothole or if there were more safety features, even maybe better jackets and jeans that have padding in all the right places to support falls, I’d think we’re moving in the right direction. The gotcha is that we’ve had time to understand what bikes and cars need for safety but we haven’t had as much time to understand what makes for a safer scooter ride yet. Likewise e-bikes too, if you ask me. And jury’s still out as to whether or not bikes or cars have “solved” their safety issues completely.
I should say that scooters are definitely still improving. A new latch design is slightly better than the old one, suspension can help maintain balance in some situations but not others, and some scooters have anti-skid technology so the front and back wheels always rotate at the same speeds at the cost of a loss of power going up hills sometimes.
Short of a true hoverboard, the answer may come in emulating wingfoils on the ocean. A third wheel drops down at speed and pushes the scooter deck into the air. Like lowering a plane undercarriage. So an e-unicycle below the e-scooter. That creates a buffer if a pothole or kerb is hit - the wheel swings back into its holding compartment and the e-scooter wheels make contact again.
Hey, and why not even hold a wing up when the battery is low!? That can also charge it up!
