Something I've noticed from the numbers we are seeing so far... On paper, Model S P100D acceleration to 60mph is one full second better than the Performance Model 3. But in real world driving, it's a lot closer than that. Ludicrous is pretty much only useful for launches where you have time to setup the option. You obviously wouldn't typically do this at a stoplight or an onramp. Or to pass someone quickly. From what I've read, P100D 0-60mph has been measured at about 2.9s if you don't take the time to prepare a Ludicrous Launch. The Performance Model 3, on the other hand, doesn't have Ludicrous (yet), so the rated acceleration is always available with no setup. P3D with the Performance Package has seen 0-60mph runs measured at 3.2s. So, in the real world, where you aren't taking several seconds to setup a launch, the difference in 0-60 between a P100D Model S and a fully optioned P3D is only about 0.3s. This also applies at the track (other than a dragstrip), where the Ludicrous option pretty much would never be used.
