Are taxi drivers paid hourly?

Nope. They usually keep what they make. They usually give a cut of the revenue to the taxi company, people who they lease their taxicabs from.

It depends on the city though. In some, they pay to lease the taxicabs (the actual vehicles), and they get to keep all the money they bring in.  In others, you give them a percentage of what they brought in.

I think bus drivers and train conductors get paid hourly. I mean, I have no idea but I assume.

are you asking if how much they make, on average, in an hour?

Taxi drivers, like rideshare drivers, are usually independent contractors. I don't know if any of them get a salary. 

Perhaps in small towns with small taxi companies? and maybe limo drivers like airport transfers.  That's a whole different ballgame though.

No. They do not.
