The point is, this is beneath Lexus to be even spending time on, or focusing on this technology. This is a very standard technology, that as you mentioned, has been used on Toyotas for many years. Also a number of competitors have used this technology for years as well. There is nothing 'new' about it.
uh, why? You have no idea how it works and how effective it is in LS, but it is beneath Lexus? Do you think it is exactly the same thing they had in Crown in 2007? I very much doubt it.
