I would pay extra because I don't want the cognitive load of haggling on the cost. When I want/need A ride, it's because I'm either overloaded, away from home, or drunk. These are three times that I didn't want to bother with any more nonsense.

One anecdote for a datapoint: Not sure if it's better now but I've lost a phone in an InDrive and I've lost an expensive bag in an Uber and it was significantly easier and less sketchy to get the bag back. I'm not a price sensitive rider so the insurance of a reputable 'comfort' tier Uber driver paid off. The InDrive driver made me get another ride to him then demanded $1000mxn (~$55usd) to return my phone. The Uber app had me pay ~$250mxn if I remember correctly and the driver promptly returned the bag.

People like the knowledge that they are not being ripped off by the person they are interacting with. On Uber you are essentially guaranteed that you are paying the absolute max that you would accept algorithmically, and the driver is getting the absolute least they would accept to drive for. If the balance shifts in any way, someone is ripping off the person they will interact with.

Since the customer knows less about how much things should cost, they are more likely to be ripped off. People pay a 30% premium to ensure that they dont feel ripped off alone.

Can't speak for InDrive's safety rating, but I would pay 30-50% more for Uber's safety tech (on a $5 ride) than a company with less funding.

Insurance goes up. Who knows how much liability they need to cover transportation. They likely deal with claims of being kidnapped or held hostage by driver on a regular basis.

Man in some of the shitty countries I've had the misfortune of living in, taxi drivers were outright predatory and sometimes downright hostile. Uber was a godsend in such environments.

30% is fair. Don’t like it start a cab company
