    Hi fellow Tesla fans,

    It has been quite a while since I last posted, good to be back. I finally pulled the trigger and my 70D is being delivered next month - can't wait! I have two questions for you all in the meantime, one in this post and one I will put in another post.

    Q: has anyone tested indicated vs actual speed using an independent GPS, particularly at freeway speeds? Reason I ask is that most cars I have driven are out. For example, at 115 actual (GPS read) speed my Nissan indicates 122 on the speedo.

    Thanks
    Justin

    I did it with a speed app on an iPhone and at 100 the Model S seems to read 2 kph fast. So I set my autopilot speed adjust to +5kph and I'm cruising 3 kph over the speed which (so far) gets ignored :biggrin:
