I’m a new P85 owner. My previous experience includes BSEE degree and 40 years in computers and IT. I bought/received an “inventory” demo/loaner car two days ago. FYI, the discount formula for the current sale of inventory cars is $1,000/mo since delivery plus $1/mile on the odometer. This can yield an attractive discount. It allowed me to get the P model which I couldn’t have justified otherwise. I had read the owner’s manual cover to cover, watched the videos and read the forums. I LOVE this car more than any I’ve ever owned (last one was a BMW 540 Sport) and continue to be surprised by the smart, intuitive interfaces. I have a few observations to add to the things I’ve read in the forum. My car was delivered with 5.9 software.
Based on extrapolation of shorter observations, my car loses an average of 1.8 miles per day when asleep. There are differences in rated, estimated and ideal mileage but 1.8 is the average.
If I leave VisibleTesla 0.26.00 open on my laptop, it keeps the car awake which makes sense because it polls every “n” minutes. In this mode it loses an average of 19.6 miles/day, again based on a sample of a few hours. This seems consistent with the stories about the bad 12V batteries that also keep the car awake.
One of the 5.9 additions seems to have a bug. Every time I get in the car it asks me if I want to define this location as “Home.” I don’t for security reasons so I touched “Don’t ask me again” but it still asks me every time. I hope Tesla reads this.
Several times a year I drive to the Orlando FL airport to catch a non-stop flight to Texas to visit my kids. The round trip is 250 miles which is very touchy considering that 95% of the drive is on Interstate and I really don’t like driving my P85 in the slow lane at 60 mph to increase range. I contacted the off-site parking company I use, Park-to-Fly, and they said they have parking spots with available power. No extra charge was mentioned. I don’t know what power is available but even 120V/15A would completely charge the battery while I’m gone for 4 days. I’ll report back in a few weeks on how that goes. The Orlando service center offered airport delivery/pickup during business hours but my return flight is 8 pm on a Saturday so I don’t even want to ask for that. They’ve been great for all my other interactions so far. If this works out, it solves one of my two major concerns. The other one will be solved by the undercarriage battery protection announced 3/28 when I can arrange it.
