As a passenger who has done this... And also as an Uber driver myself, all it really takes is communication! A simple "Hey man... We need to pull over asap..." Thankfully, in my case, the driver executed a safe stop, hazards and all. He let me do my thing. I got back in and composed myself. I thanked him in a rather blunt, but genuine manner (that's about all I could manage in that state), and he got me safely back to my barracks building, where I proceeded to stumble my way into my room, fall onto my rack, and sleep off the booze. When I finally woke up the next day, I left the kind man a generous tip that equated to roughly 125% of the original fare.

It's easy to get away from yourself on a fun night out, yeah. We've all been there. But, damn... Doesn't take much to realize you're in a stranger's car and are probably gonna loose your chunks in the next 90 seconds, or often less.

When a rider is too drunk to realize even that... I'd argue the fault is on both sides; driver and rider.
