I agree with you. I understand that how you behave as a member of society is useful information and it's valid to not hire a jerk. Having the taxi driver as a spy is a bit like bugging a confessional though. Like you say, if they really limit the taxi driver's input to "was he directly a jerk to me", that sounds ok, but like any surveillance, it's unlikely it really remains limited to such a fixed scope and other information doesn't come in and bias the answer. A taxi is where a lot of people feel safe from observation, and may say things not meant for anyone's ears. As an aside, I'm always shocked at what people will start saying in a taxi/uber, particularly I'm thinking of talking about confidential work stuff. My personal view is you never know who the driver is and loose lips sink ships, don't say anything in front of him that you wouldn't say in public. But I know many don't see it that way.
