That's my impression. Their prototype likely can do 0-60 in 3.2 seconds (without roll out) assuming Autocar doesn't use roll out (it's in the UK so most likely not), but so far no evidence the actual production model can do so. I wonder if Elon did have an F1 on hand to compare with P85D during development.
Mclaren doesn't want you to test it, and no Mclaren owner wants you to test their car, because you'd probably destroy a half million dollar powertrain in doing so. Which brings me to my next point, this debate about rollout vs no rollout is inane. All standing starts for ICE cars are incredibly abusive and not something you can do almost anywhere. You _should_ be looking at 5-60 times to remove "launching" from the picture. That will add a full second to almost any ICE car's 60 time. If you had a turbocharged engine, add even more time.
