http://www.engadget.com/2008/05/29/toyota-rolls-out-night-view-equipped-pedestrian-finding-crown-h/Now this is not a new concept in a car and has been posted before and a while as a concept and in the odd expensive car on sale and even this one from Toyota the people detection is nothing new as a technology but there is more to this really.
Tests as discussed before on these forums and shows like 5thgear, top gear who mention that tests have shown that nightvision in cars improves visibility and driving at night, since you glance at your speed so you glance at a screen to see.
Now of course the full blown effective outcome is for you windscreen to be fully digital and house all the information you need and switch to night vision mode at night etc and you would not need ligts in a way but that is many many years off.
My point here though is that while you got some different variations is it not time /cost effective enough for an lcd to replace your dash and have the ability to do rear view display and night vision etc. Again they are in cars but Just as ABS and (what is the new one that stops rolling etc?) etc I think this is another standard feature of a car that should be included in all from the cheaper end to the high class cars.
I mean what does an lcd cost these days and even some form of night vision is in the cheaper cameras
