Right, that's a good way to compare. Trouble is there aren't that many Teslas around here and for now I don't want to go for a test drive with a new one.
I did try one more thing in the mean time. I recorded the dashboard, cropped the video from where 0 turned to 1 and where 59 turned to 60. No matter how I count, it's still around 5 seconds.
I had to schedule a service visit anyway (some play in the driver seat) and I started with the uncork request. This time the app didn't give me a mobile service option, it scheduled me to a nearby service center next week. We'll see what they say.
