TechGeek Tesla 🔋⚡️(@JonBbC_TechGeek):.@AIDRIVR showed FSD on HW4 reacting in 0.130 seconds. However, this was the reaction time on the screen only. It’s important to evaluate when FSD takes action to reduce speed or move the wheel. For this, I found 0.267 seconds. But how about HW3? I did the analysis here and found it to be 0.567 seconds. This is equivalent to an alert driver’s reaction time according to an MIT study. Not bad at all! Thanks to @DavidMoss and @koby_pierce for making this evaluation possible!
