As much as I love meeting interesting Uber drivers, sometimes, I'd be so stressed and/or tired that I'm in no mood to talk to or up for a conversation with the uber driver. However, unaware of this obviously, the driver tries to engage me in a chit-chat which further irritates me but I wouldn't be let it show on my face just to be not rude. It's difficult to tell them that I'm not up for any conversation. So, while booking the ride itself, if there is a checkbox or something which lets the drivers know that the rider doesn't like to converse at this moment, it would be really helpful.

Accepting cash payments.

RLY.

I avoid paying for anything in a way that I can be tracked. I avoid taking the discounts that grocery store loyalty cards would otherwise give me.

Consider that paying for anything electronically, is rather like having a complete stranger follow you everywhere you go.

You do realize you're using an app from a phone with this service? I'm pretty sure paying in cash won't do much in this case...

That's why I don't use Uber at all. For the most part I get around on public transit, that I pay cash for.
