It's probably one of those things where the salesperson is talking too much or you've got the windows down or something during the testdrive and thereby not hearing it. It's also not prevalent on all Zs so maybe they drove a different car than they bought. Mine is barely noticeable; any hard driving or loud radio masks it very well. Some others aren't as lucky.
