But these cars aren't disposable, the whole point is that they are upgradable via software, is it not? These self driving cars will hopefully improve, but limiting them because 'humans don't use radar' seems short sighted. Perhaps we would be better drivers if we'd evolved with some sort of radar. Also I'm not sure to which koolaid you refer, but if its the Tesla one you should probably know I'm extremely sceptical of their claims and have no intention of owning one.
