I agree that all these
I agree that all these factors are important. Your article isn't wrong, but it is dated. Current production models still don't have most of those features, but they do have sensors in place for reasons Tesla hasn't announced. Lane departure warning is now a standard feature. ACC isn't there, but the stem on the steering column for cruise control has the ACC markings and an additional knob for setting distance. It has the sensors that are of the type and in the location used for blind spot detection, and the use of the front sensor (possibly sonar) as well as the new camera could each or both be used in collision mitigation. The camera currently does things such as read speed limit signs.
I read this article and many others before buying the car and was particularly concerned about braking issues. Since it's impossible to step on the accelerator and the brake pedal at the same time when using them as I was taught, I figured I'd be diligent and be sure not to pivot on the heel of my foot rather than picking it up to step on a pedal. But now that I have the car, I found that it would be impossible for my foot to touch both pedals even if I push the brake with the ball of my foot, and the pedal would remain well above the height of the accelerator anyway. I have no idea if this was a result of an unannounced production change or whether any of these features were added because of these sorts of articles. I'm just glad that they are being added and that all new cars have the hardware for it.
The advantage of the Model S is that it's possible to change the hardware even if the software isn't ready, since software gets updated wirelessly. . It's a shame that there are no plans for offering retrofits.
