if Omar's signed an NDA, would he say as much as he has? On the other hand, maybe he is holding out on us for some info?

A few corrections to this.
Not “all” modern cars have this but it’s pretty common. But, when people say “variable ratio” there are really two different systems. There is this one and then there is a fully variable system. That one actually uses a device to literally change the ratio based on parameters such as speed, etc. It doesn’t consist of a rack with variable spaced teeth, it consists of a set of gears which can instantly change the angle of steering vs. angle of wheel input at any time. It’s been around for a number of years. Audi and BMW use it.
some say it’s odd feeling, others don’t mind.

Usually if you signed an NDA, you don't talk about it at all.if Omar's signed an NDA, would he say as much as he has? On the other hand, maybe he is holding out on us for some info?
Let Omar enjoy his car for the weekend at least. He will keep us informed I am sure.

On the subject of power.....
Looking at the HP curve from the delivery event (powercurve.jpg), all performance cars are following roughly the same curve slope after the P85 for the initial launch and first tens of MPH. The two primary distinctions between the P85, PxxDL and Plaid are the point at which the curves plateau and the plateau profile.
The P85 runs in the 450 hp range, the P100D in the 630 hp range and now the Plaid at 1050 hp.
The Plaid curve has a SLIGHTLY lower initial slope in comparison to the Performance and seems to be spot on the P100D.
The Plaid lays down a little bit on power as speed builds where the others simply fall off.
Watching all the videos and listening to Brooks, It occurs to me that-
The initial power delivery is likely traction limited from the P100D onward. The batteries with higher voltage can source more power at the same current levels so there is likely more power available than can be used at slower speeds. Basically, the slope of the post P85 curve is likely the sane limit of every day street car traction using very advanced traction control. There are small improvements in 0-60 but these likely will not register on the butt dyno. Brooks said as much when he said the big difference is that it keeps pulling. (addition here - the PLAID's power curve climbs in the 40 mph to 60 mph range while the others plateau. This alone will improve the 0-60 but on the tail end as opposed to the launch end. This is very useful.)
The ability of the Plaid battery to maintain that slope is the most interesting part for me. Tesla must have significantly reduced the pack's internal resistance (in combination with the higher voltage) to allow them to pull that level of power from the pack for an extended period of time. This improvement will show up as range as well as improved supercharging performance.
Coming from a P90DL, I expect the new car to launch a bit harder than my current car. This is not all that important as I have not done a running foot stab launch of my car in years. It was fun a few times in the beginning but gets old fast. In short, it will be a wash for me in my driving style.
What I see as incredibly useful is the inprovement in acceleration through 80 mph. This car will be unlike anything most of us will have driven on the street when it comes to pulling at higher speeds. It will be unlike anything any of us has driven on the street when it comes to the instantaneous availability of that power. No battery heating needed. Just leave it in PLAID and it will always be there for you. That, for me, is game changing.

Tesla folks at the event seemed pretty certain there would be more deliveries this month
Dude, album art has been broken in one way or another for 8 years
, but yes, I'll add the to the list--need to go dig up a USB-C stickYup

Engineering school was more than 2 decades ago, but I thought that 1 G was a force = 9.8 m/sec*sec acceleration per unit of mass at the earth’s surface? It should be a small g. You don’t feel any force during free fall in a vacuum (space), but you do feel air resistance while falling in atmosphere.

Well, Tesla just hates my family... My mother's June 13-20 model Y delivery just changed to July 27-August 11. But, hey, at least she has a date...
For new/refresh models yes. I was fortunate to get in on the 3. Same uncertainties and lack of communication. Frustrating. But once you get the car - man it’s worth it. I can’t think of anything else I would put up with.
Once they start rolling it’s a thing of beauty.

Someone commented about the G stability during one of the launches. I suspect the hand/phone stability is not sufficient to deal with impulse G loading so some of the input was lost.
I believe the "NDA" comment was a joke someone made (worst case: I get my car and cannot talk about it), and yeah, often an NDA includes language saying you cannot acknowledge it exists, but, no, I am not under an NDA from the Plaid event. You guys are making the journey with me and doing my best to keep everyone updated.
My S showed up a month early (yay, batching). Our X (prod VIN 4xx) was 2+ years late.

3 decades for me...
What you mention is an acceleration, caused by warping of SP, counteracted by a force of atmospheric drag, or the normal force of the earth.
Not an easy concept, but think about it.
My point is a free fall will not give you the force feeling of a plaid. Catapult launch would be closer..
Never! Y'all are my peoples!

Fellow Florida resident,
I COMPLETELY agree with everything you just said. I just can't get that power curve out of my mind. talk about area under the curve! What curve...LOL! I peak power all the time (except lower speeds). I said this the other day I never thought this was possible to have that kind of instantaneous power. This is a gamechanger, and an engineering marvel. Not sure everyone fully realizes this yet. This car is going to devastate a lot of multi-million dollar cars.
Also, good observation on the power curve at the lower speeds.

That was me. I was just trying to determine the factors as to why to 0-60 was only 2.74. I now realize the air temp was like 57 degrees and the road surface probably created a traction limited condition. There were 3 people in the car but I am not sure that would know the 0-60 time down by .7 sec? maybe it was a combination of both items....I have no doubt this car will do what Tesla said 0-60. Too bad it could not have been tested with the Florida sun bearing down the road for a few hours....lol
Getting a SW update--will report back once its done (~50 min)
