The reaction time really is faster than I expect
From the Driver’s Seat · Jun 20, 2026 · v14.3.3
AI DRIVR said Tesla's "20% faster reaction time" claim was an understatement, and I think he's onto something. I can't put an exact number on it — the situations vary so much it's hard to measure from the driver's seat. But the feeling is consistent: the car reacts quicker than I expect it to. Almost every time something happens, FSD is already on it before I would have been. Whether that's exactly 20% or more, I couldn't tell you. What I can tell you is that "faster than I expected" has been the rule, not the exception, on this build.
