Oleksandr has been your go-to Uber driver for weeks now. Whenever you need a ride, it seems he's the one that shows up. It's convenient, he knows the city well and your preferences. However, lately, you've noticed peculiar moments during the rides. Oleksandr's usual chit-chat has turned into a constant stream of scripted-seeming banter, as if he's reading from a script. His directions and knowledge of traffic patterns seem too spot-on, almost inhuman. His overly perfect English, despite being a native Ukrainian speaker, is off-putting. Just yesterday, as he dropped you off, he mentioned a secret memory from your childhood, something only a close friend would know, but Oleksandr isn't someone you've shared those details with.
