I chat with the driver unless I'm in a crappy mood. You often learn so much about people and form a connection - even if it only lasts for a few minutes. That said, not everyone's personality works well with talking to a stranger... and it has to be a 2-way street (i.e. they must also want to chat. I've been with drivers that just want to listen to music and drive you without interruption )
