They made a TSA Friendly E-Scooter

And its here - well on pre-order.  Fully funded in 5 hours.  

EcoReco is not new to scooters, they've released quite a few over the years but this one has a lot of important (to a lot of people) features.  Easily switchable batteries, TSA compliant setup (can remove battery from scooter, and TSA compliant kWH battery capacity), performance, and fairly portable.
