Earlier quoted context omitted.
Paid per hour, free to chose their working hours, free to work for multiple employers at the same time, etc. How are they not contractors? They're way more contractors than the contractors that were working 9 to 5, 5 days a week, for years, for my FAANG.
I do not think they can choose their working hours, their income does not allow this freedom. Not US, but I did some study on Ukraine immigrants in Poland, etc, they work as self-employed at factories, like LG and Samsung and even make some parts for Porsche cars. A luxury made by slavery, 12 h/day, 6 days a week and minimum hour rate.
Drive when you want, make what you need
Earn on your own schedule.
They can't force you to pick someone up.
