There are several ways to make money from your car such as taxiing people, renting your car, or advertising businesses. Run the numbers before using your car to make money, especially if you're driving more than usual because it might cost more than you earn to use your car as a money-maker. Factor in depreciation, wear and tear, and gas expenses when you decide if driving is a cost-effective way to make extra money.
Along the same lines as trivia, you can get paid for just using your mobile phone and allowing companies to know what you're doing on it. For example, Nielson Mobile Panel is an app that you can earn rewards on just for having it installed. It will take snapshots of what you're doing and use those for advertisers to know more about your demographic. It takes away some privacy, but you get paid for it.
If you’ve got some free time and don’t live in the middle of nowhere, becoming a Lyft driver can be a very lucrative side hustle that allows you make money fast. And right now, they’ve got a promotion going on where any new driver will instantly get a $300 bonus after completing their 100th ride. If you start now and hustle hard on the weekends, you can probably unlock that bonus within a few weeks of driving (and that’s in addition to your normal earnings).
