Progressive taxation rate that can go negative (aka people can receive money) is more fair.

Could even be easier to implement because it is not only a “social” benefit that cost tax payers money. That could help convince some people.

Not really.

Assuming you are alone in a car, you will be easily at 6-8L/100km, while flying in economy class you will be around 2-3L/100km per person, depending on how much they sardine can you. Airplanes are actually incredibly efficient, we simply travel much further with them.

DVDES-910 no need to thank.

About bicycle maintenance.

I’m kinda disappointed by the shoes racks experiment. Like they put a UV light in an enclosed shoes rack to remove odor and that’s it.

Of course it degrade the shoes, at 4 minutes it start to create the smell of burnt rubber…

More research is necessary
