Do you think they will/should change this? I understand the radar can't see an obstruction above x feet, but that doesn't do any good when the car is x+y feet

Do you think they will/should change this? I understand the radar can't see an obstruction above x feet, but that doesn't do any good when the car is x+y feet tall. From what I read about humans, you need +/- 30 degrees up/down vision to get a license (varies by jurisdiction). And we kill a little over a million people each year on roads. Not sure what this should imply about a car's radar though.
