My hot take is that we get full automated commercial plane before single pilot.
Single pilot means that there is no way to avoid an air Berlin like mass murder (and being locked alone in a cockpit doesn't sounds great for mental health). No pilot means less risk to have such a scenario
Sure we need risk analysis (accident caused by humans versus humans preventing accident) and most likely newer ATC protocols, and some upgrade in equipments, but I doubt there it a major obstacle.
Bicycle lanes are always a chicken/egg problem, If you build safe bicycle lanes (and not just drop some painting on the road without changing anything else) you'll drag more cyclist, which in the end let more space on the road for people who really need it. It's annoying for the car-drivers, but it's not like car aren't annoyance for the rest of the population either. Too many cities gave the priority to car in absurd proportions.
Regarding traffic code, it's a complicated topic, there is some minor changes of rules which are really making cycling more efficient, I am thinking about the right-turn on red or the dual way bike-lane in single-way street (when technically possible). On the other hand, some cyclists indeed ignore every possible regulation, all while not having the experience to understand what's safe and what isn't
