My experience is with bikes you can easily take one hand off the bike to signal a turn - what your traffic intention is. But with the scooters, it's not really possible to take your hands off the handlebars (you lose control!), and there is currently no blinker control to indicate your traffic intention. I wanted to take a left-turn on a scooter recently and this was an issue. I got honked-at.
I think they should add blinker light controls to the handlebars.
I think the scooters are riskier in some ways. My experience is with bikes you can easily take one hand off the bike to signal a turn - what your traffic intention is.

Coupon books are used in France. One coupon for each candidate. Voters privately choose a coupon from the book at the poll site and put it in an envelope. They're distributed and counted by volunteers very quickly and there are checks for integrity. A final count is ready for the evening news. There is a full paper trail. Very hack-resistant!
I've heard it said, "A data scientist is a better statistician than a typical programmer and a better programmer than a typical statistician."
I 'graduated' from the Data Analyst Nanodegree @ Udacity in my spare time, and have experience with both. I lack a background in math beyond university Calculus, though, so that seems the major barrier for me to get a foothold in the industry.
A bit oversimplified, but in France, voters are essentially given a printed coupon book, with each candidate on a different coupon.
They just take their coupon/candidate of choice and deposit it into a box.
There are no pencils needed, no ambiguity. Ballots are hand-counted and totals are reached rapidly. A far less-hackable alternative to what exists in the US IMHO.
I'm a huge fan of ZMM and I enjoyed Lila - where he elucidates a metaphysics of quality. His writing is brilliant, but my theory is that he may have experienced mental distress, in part, because quality is actually _subjective_, not objective. He attempts to elucidate and objectify something that fundamentally depends on a point of view / perspective.
Ruby on Rails or Node.js for the backend (API) and React for the front end. Rails is excellent for database migrations. Postgresql / MongoDb / Firebase for the database, depending on requirements.
As a US driver living in France, I can share just the anecdote that French driving far less pleasant, more stressful, and feels more dangerous due to its narrow traffic lanes. I can also report seeing high numbers of highway accidents in Paris, and I would be surprised if per capita traffic fatalities were lower in France. I dream of driving in the luxurious, relaxing wide lanes of the US.
I'm curious if they looked into pf / CARP as part of their research into allowing horizontal scalability for an ip. See: https://www.openbsd.org/faq/pf/carp.html
