I called the Didi special car yesterday. When I got on the bus, I found that the driver was my ex-boyfriend and didn't talk all the way. Did he not realize it was me or didn't want to talk to me?

You ask this question, which proves that you still care about him; Personally, I think that if you already have a boyfriend, or he already has a girlfriend, then you'd better not bother him. This is a kind of respect or protection for each other. If you are both single and still have feelings for him, I suggest you re-examine why you broke up, whether he is really not suitable for you, and then make a choice whether to contact her or not. If you are just curious, I suggest you forget it. Now that we have broken up, it is a good choice not to disturb each other. Generally speaking, if you can still be friends after breaking up, there will always be contact. The best way to be friends is never to contact unless you want to get back together.
