Thanks everyone for the feedback. Looks like mixed experience so far. I think @Sawyer8888 summed it up best. "Adding EAP does not make sense, but it is a must." The follow-up question I have: Tesla touts Model S' safety. However, many of the safety features including forward collision warning, blind spot warning, lane drift warning, etc. are part of the EAP upgrade if I understand correct. Shouldn't they be standard features for a $70K car? Also, it seems some of those basic safety features are yet not functional. I understand Tesla still needs to make money for all this tech, but if they are putting all the tech in the vehicle anyway, wouldn't it be better to bundle EAP as standard for another $2K to the base vehicle price for everyone rather than charge $5K as an option? That could be another key way to differentiate between M3 and M S/X.
