I don't see any reason that Launch Control doesn't come to 85D.
Maybe they are just trying to open the gap between Performance models vs 85D.
As much as I'd love launch mode, I doubt it's coming for us just because I think Tesla wants to make the feature exclusive to performance models. However, what does keep me a little optimistic is the sport mode update we got in early April, making us the first non P model to get an acceleration mode selector. They did remove it eventually replacing it with Sport mode all the time.

I think the reason for launch mode is simply to reduce the stress on the drive train.
1 foot rollout still shaves off ~0.3 seconds from the number and when it's standard convention to do so for USA car magazines that is relevant for comparison purposes.Given that any form of electric motor (circular saw, blender, etc.) makes max torque from a dead stop, why would they want to measure time from a 1 ft. rollout?

The number is a rough estimate and will obviously will vary by car (since acceleration in that range and the circumference of wheels will vary), but ~0.3 seconds is a very good estimate that covers a wide range of cars. 1 foot is only 1/6-1/7 of a turn of the wheel. The acceleration within that range isn't going to vary that much.Technically, the car has as long as it wants to cross the 1 foot mark before timing starts.

Great description @SomeJoe7777. I'm new to drag stuff and I've tried to read up on this, but I feel like you summed it up nicely.
BTW, Motor Trend's latest newsstand issue dated February 2015 has a 3 page Tesla P90D article. A must have for the P90D enthusiast.
