I just purchased the new Model S Raven Long Range. I had a MS 75D previously. After getting the car home I noticed that my phone app no longer had the summon feature. I called tech support and they have advised me that the Summon feature is now only available if you purchase the Full Custom Driving feature for $6000.00. This feature was in my 75D. I can understand Tesla making the Enhanced Summon feature an item you need to purchase, but certainly not the standard "back my car up" summon feature. This was a decision made some higher up at Tesla without considering the benefit to the regular purchaser of the Tesla. A very short sighted decision that probably would cost Tesla nothing but add great goodwill with its customer base.
