I think the answer is what Tesla is trying to move towards, all vision based, which is fine but the cars stuck without having anything is kind of adding another list of items to deal with on the "upcoming release". Likely have to deal with $XXX retrofit kits and etc.It cannot detect curbs or skinny poles. It gives a false sense of confidence and can lead to accidents. That is why I think it's useless and needs to be replaced (industry-wide) by something better.
