Pros
You got to meet new and interesting people all the time. You get to have interesting conversations with said people and Be Your Own Boss and set your own schedule.
Cons
If the city you're driving in is oversaturated with drivers, then you have to compete for passengers. Too many drivers and not enough population makes for lower salary. Lyft has been stealing from their drivers, saying that they are paying their drivers 70%. But they take out a lot of money for taxes, fees, and insurance. They give you 70% of whatever is left over. Recently I drove someone and it was a $75 ride. That's how much I was supposed to get paid. But after taxes and fees I was only paid about 2/3 of that. Now think if it was a $1,000 paycheck, you would only get about $600 of it. They should incorporate the expenses into how much the writer pays, not out of the driver's pay
