If I got a McLaren for free a year ago, I'd have traded it in for a M3P and then invested the difference in Roadster deposit + account with interest.

Model 3 Performance Test Drives

Yes and that's what's so neat about Model 3P. in the dragstrip video, the newbie toasts the guy with the competition M3 who spent $10,000 more money and obviously was way more invested in the race. Anybody can drag race this thing and get close to max performance.
I'm not sure but I think the ET excludes the reaction time, and is based on when you trip the light that is 1 foot forward from where you are starting. I could be mistaken but I think that's correct. Does anybody else have definitive information about this? Also if your reaction time is below a quarter of a second or so (Fastest anyone has ever been able to react to anything I think is on the order of 200+ ms), they assume you've tried to "time up" the light and you are DQed.

Correct- RT has no impact on ET at all.
The timing light thing is where rollout comes from, which is why you can't trust vbox 0-60 times to tell you "real world" 0-60 times (draggy on the other hand doesn't include rollout in their 0-60).
Hence why some people mistakenly think the P3D runs 0-60 in 3.2, when the 3.5 from Tesla is quite accurate for a real world 0-60...for the 3 Tesla advertised all the 0-60s without rollout.
(The S/X on the other hand they explicitly include rollout in their P model 0-60 times)

As @Nightshade said; RT has no effect on ET. To your question, there's a text note late in the video briefly mentioning that the McLaren driver was playing with launch control, explaining his RTs.

So most car magazines do their testing on a track and include rollout in all their numbers (often using vbox)
draggy works slightly differently- it includes rollout in their 1/8 and 1/4 mile numbers- to reflect how things work on a track... but does NOT include rollout in their 0-60 (or 0-X) numbers because in real life you're not doing a stoplight race with rollout.
Vbox came first- and thus became a bit of a gold standard even though their 0-60 numbers end up inflated due to rollout- but Draggy results appear to better reflect the actual numbers you can expect under the actual conditions you would care about them.
FWIW in the comparisons I've seen draggy actually better matches track times too-
Track vs vbox vs Dragy results
Me? I first got into performance cars before GPS was in common use-so I've got an old G-tech accelerometer that still works fine as long as it's level/mounted correctly...fast-polling GPS units are marginally more accurate and more forgiving of placement/calibration concerns but I'm not running a car magazine testing tons of cars so haven't seen a cause to upgrade... and honestly even less so with the Tesla, unlike previous cars it's not like I'm gonna be hooking up my laptop to tune the ECU or anything.

I got a call to come test drive the performance model 3 today! I put in the request like 3 months ago. Shame I picked up my P3D- a few weeks ago already!
This is really a big point, and it makes it clear that people are often times comparing apples to oranges. I think the more accurate way to do this is to exclude reaction time in other words with a rollout. Otherwise you're talking about adding a variable interval to the actual acceleration interval to reach the target speed. What was a bit weird though is the Tesla appears to quote rollout-based times for their ludicrous mode Tesla SP 1000, but not for the model 3 performance version. It seems to me that all 0 to 60 times to be meaningful have to include clarification of rollout or no rollout.

Okay, not my field, but how are reaction time and rollout connected? Staging depth and rollout, but RT?
