Just recently test drove the S and X models. Neither car had blind spot detection in the mirror like my current Lexus ls 460 ,when will this be added? The mod S did not have adjustment for the seat belt and cut across my neck any plans to add ?

I feel Conner Spies has aptly answered both issues..nothing more to add.... except Advisors at Plano go all the way in answering any query...so do visit if you have any more doubts..

The Tesla X and S both feature blind spot detection, which is far more developed than that featured on the IS460. Although its not integrated in thr mirror, both vehicles will show you all obstacles and traffic around the car in the screen where the spedometer is located. This will likely not be added in the future, as Teslas cars are designed to be driverless, removing the need to check mirrors altogether! (Pending legislative approval) Hopefully this helps!

Don't know but you could probably get the answer from an associate at the Plano showroom.

Yes, Tesla is adding it.
