Unethical practices are tolerated, and somewhat encouraged or coerced indirectly by staff/management. Supervisors (who are mostly former drivers) will tell you that "your numbers are down for the month," and give you not so subtle encouragement to start taking advantage of tourists. They do this by 1) assigning cars and shifts based on monthly performance, 2) if you are not assigned a permanent shift, then you are given the worst car if you do not produce sufficient numbers, and 3) threatening to fire you if you do not have high numbers. Moreover, they will assign you a driver/supervisor who will tell you to long-haul (this is the practice of taking the long way to increase the price of a trip).
Your coworkers *can* be utterly intolerable. There are some honest, hard-working drivers who are at the company. Others are immigrants who feel cheated by the system, or are morally base for whatever reason. Most US born drivers have some sort of addiction, or life leak that lead them to be drivers in the first place. Some do not shower, and most of them are overweight blobs.
In regards to them being overweight, you will find out how easy it is to become out of shape after working as a driver. If you want to make money, you have to hustle. This means taking as short of a time as possible to get food. I'd recommend bringing your own lunch in a small cooler and keep it in the trunk. This will cut down substantially on costs, and will help you maintain a regular weight. Moreover, I'd recommend stretching and doing squats while waiting in line for a ride. No matter how you spin it, you will be spending most of your time every day in a vehicle.
If you have any desire to change the company, or to be rewarded for honest performance with the company, then find a different career. The Taxicab authority will not/does not enforce preventing or rectifying unethical behavior either.
You will not thrive financially, you will survive. You will not make a substantial amount of money, and companies like Uber will eventually monopolize the industry.
