That's not true at all. From the text of prop 22, the minimum wage covers the entire period "from when an app-based driver accepts a rideshare request or delivery request to when the app-based driver completes that rideshare request or delivery request."

So it's true that if you're sitting outside an airport at 3am when no one is there you won't be getting paid. But as soon as a plane lands and you accept a passenger, you'll get paid for the time you spend driving to pick them up AND the time after you pick them up.

Similarly, if you accept a food delivery in the app but the food isn't ready when you get to the restaurant, you'll get 120% minimum wage while waiting for the cook to finish
