If Uber was based around this kind of thing then I would support them. Their current business model (for the most part) is one person going to one place. It's identical to driving everywhere yourself, without the hassle of parking.
I don't know about you or the guy above, but I pretty much always use Uber Pool/Lyft Line over the single rider versions when it's just me unless I'm in a huge rush. Most of my friends do the same, and I started using both services more then they introduced the feature.
