See my other comment here but this is exactly my point. On a bus with dozens of strangers I have 0 recourse. In a car with someone who at least had to provide some kind of ID, I have more power. Consider that strangers just being present is not likely to protect you. EDIT: I don't think your original comment included the licensing bit (apologies if I just read it poorly), but it doesn't change my point. If you have to provide some paperwork, however illegal, however incorrect, it is a barrier to crime that public transit does not have, and is a paper trail.
