Consiglio: If your passengers comment on the road conditions and other traffic, your driving might be making them uncomfortable

Unless something exceptional is going on, road conditions and traffic are really boring and not something worth commenting on. In fact most passengers would rather not be paying attention to the road at all.

So if you notice your passengers frequently making comments like, “Whoa this lane is narrow” or “What a huge truck!” they could just be too polite, or worried about your reaction, to say “Whoa this lane is narrow [that you're speeding along],” “What a huge truck [you're passing on the wrong side],” etc. There's a chance that your driving is making them uncomfortable. At the very least, something is making them pay attention to the road instead of their phone, radio, conversation etc.
