The principle here that matters is "personal electric low-skill vehicle". Segway tried it first, but electric scooters were way cheaper, and the GPS/smartphone technology helped it a lot.
Dean Kamen is so cool to me, because he's pretty unknown but has had such a positive impact on the world, especially with his STEM outreach to school kids. I got to meet him once briefly after the FRC national championship in 2014, he was going somewhere but still stopped to talk to us briefly and I thanked him and he signed my team hat.
