content: Yeah I don't dispute that. But if the camera system was intuitive enough and the operator was well trained on using it, it seems like you an accomplish much of the same thing more simply. I think camera systems could have a lot of potential. For instance, they could display the feeds from other fixed cameras like on the buildings that the driver might not necessarily be able to see even with an elevated view at his current location. But yeah I don't mean to say nothing about this is useful, but the benefits over other solutions don't seem like they scale very well with the complexity. But I'm not married to my stance here and could well be proven wrong. Was just my initial uninformed assessment.
