I imagine because a huge part of optimizing fleet availability and distribution is knowing where you want to go before deciding which vehicle you should travel in.

Ah, yeah, that's a good point. I can imagine some potential creative workarounds (e.g. having certain rides or types of rides involve transferring between two vehicles, possibly with multiple parties per vehicle like Uber Pool), but whether they'd actually be willing to support that is another matter entirely.
