I just found out my sister & I were being taped by a taxi driver

Basically, before I got in the taxi I saw the driver turning on his phone’s back camera. I denied that at first. But then he kept his phone in his hand while driving with the back facing me and my sister so it gets a full view of whoever is sitting in the back). And he kept looking at us through the rearview mirror. I couldn’t get off the taxi since most of the road was dark so I faked a phone call to my dad and loudly told my sister that he was waiting outside our house. And ended up telling the driver to stop us somewhere 3 min far from our address so he won’t know our real one. My question is can this video make us a target for anything in the future (our faces were really clear in that)? Any idea why would he do that? And can we protect ourselves knowing that we’re two females (25 and 22) living alone?
