It might be a starting point for blackmail, but if someone is doing something blackmailable then that's a separate problem. They're a liability and I'm sure far more effective means at finding such vulnerabilities are already being employed. They're going to need something more concrete than ride data to effectively blackmail someone, anyway. "Give us the launch codes or we'll release that you took an Uber to this address!" isn't going to cut it, I think.
