He had some complaints about Pool as many around here do. I haven't been able to get a response to this question, but my understanding is that in both Uber and Lyft, whether pool, line, X, that if you want to take a break (even if you currently have a pax on board) you can hit something like "Don't Accept More Rides after this Dropoff and Go Offline."

I had read this is a way with Pool or Line rides to ensure you only have to take 1 passenger. Do you know if this feature exists?

Last ride exists only in Lyft, to my knowledge at least. You can log off during a ride and Lyft will automatically not send you anymore requests and log you off after you drop off passenger.
