One can think of the cost as $5000. Or 10% of the cost of the car. Or $80/month. What does it buy you? According to the configuration screen: * Auto lane changing * Autosteer * Automatic parking * Summon Is there more? Is there less? What do those mean to current or prospective owners? Here the guy demonstrates how Model 3 parallel parks itself. Neat, but will we use it? In a spot that wide, I would probably park faster. In a tighter spot, would the car be willing and able to do it? Auto lane changing. Here the guy discusses how it works, but is unable to demo it because of too much traffic. He mentions that he is reluctant to use this feature because it uses radar, not cameras, and Tesla may not be able to react to a car that's quickly coming up from behind. He points out that the auto lane changer is mostly useful as a mechanism to NOT switching off autopilot when changing lane. So, it's not like Tesla can change lanes better than you (unlike, say, keeping safe distance in a stop and go traffic or parallel parking, which I think it can do better than many drivers), but it's more to eliminate the inconvenience of having to reengage autopilot after a manual lane change. Autosteer -- what is that? Summon -- sounds neat, but see auto parking: how often will we use it after we have impressed all our friends once? One other way to look at the $5000 or $80/mo is that it's a prerequisite for future software enhancements, including full self driving. (I am NOT planning on paying $3K for FSD at this point). And yet another way is to say that it can be purchased later for $6000 if either a)exciting new features are added or b)after driving for a while one realizes that the four features above are what is missing. Which way did you look at it?
