I run a similar setup, but with syncthing as the syncing system. Every time I connect the phone to the charger it just syncs the database and I can even sync it outside the home network. Works like a charm. Worst case you get a sync conflict which is easy to solve.

You don't need a licence if they are in the category of electric bike, meaning they cannot be self propelled (you need to peddle) and they have a limiter limiting the speed to 25 km/h.
Unfortunately, these things are wicked easy to circumvent. Many retailers will sell you a throttle (meant for moving the bike while walking with it) and changing the speed limiter and peddle requirement is as easy as going into the software settings. This results into what is effectively an electric moped without the licence plate and requirement. According to the law, such a vehicle requires you have a license and wear a helmet, but of course nobody does.
What you need are good laws, not so much a 4 day work week. I just go to the doctor during office hours and tell my employer I have to go. I even get paid time off for it, like everyone else working in this country. Same for the dentist or any other kind of medical thing.
Sure, it's not always optimal if you work in some sort of shift, but they are required to make sure you can go.
By the way, not that I wouldn't appreciate a 4 day work week, but this seems like a bit of a stretch to say that this is the reason why you would need one.
I disagree. I absolutely love the fact that I can just turn it off after office hours and throw it in a corner during holidays and weekends. Sure, it's a bit cumbersome to take two phones with you, but it's also cumbersome to take the laptop and everything with you all the time. Just put it in the same bag and you're good. Good to note, my employer provides me with a phone, so I didn't need to buy a second one. It also means that if I switch jobs, I just return the phone and still have my personal device.
But if it doesn't work for you, by all means, don't do it. For me the good outweighs the bad.
From personal experience in Europe, I can tell you that it sounds great in theory, but it's horrible in practise. I get routinely blinded by headlights here and I feel like it has only gotten worse with the advent of LED headlights.
