Just got my new Tesla S-100 and noticed that there was no blind spot warning on this supposedly technologically advanced car! On my previous Audi, when attempting to pass if it was not safe a light would flash on my sideview mirror and there would be a beeping sound. The only thing the Tesla has is a model of the car on the dashboard and concentric gray circles appear when there is an object close to the Tesla. Unfortunately by the time one sees this it is too late to pull out and pass! Does any one know if a software update is planned to solve this issue? Addendum: Just returned from a drive on the highway with my local service department's lead technician. He confirmed that despite what the salesman told me before i spent all that money on the Tesla, that it does NOT have any blind spot warning system (like our Volvo or my 4 ye. old Audi) which can inform the driver that it is safe to pull out in the adjacent lane to pass or return to another lane. The concentric circles on the dashboard appear way to late for this to be safe. Interestingly enough when we had the car in the full autonomous mode when you turned the blinker on to pass, the car would not proceed into the next lane unless it was safe to do so! If it can do this, why can't they design it to do something similar in regular drive mode? Can anyone help me with an answer to this problem? Is there a software update planned? I called Tesla's 800 help line, but they informed me that there was already a visual and auditory warning system in place to help the driver determine if it was safe to pass.
