A YouTuber measured how Tesla's FSD hardware and software versions affect reaction time.
Hardware 4 outperformed the older Hardware 3, but the real kicker is how much quicker Tesla's new v14 Lite software was on HW3 than older software on the same computer.
It shows that a mix of hardware and software is needed for best safety and performance.
How quickly does your car's automatic emergency braking work? The answer depends on both the car's physical hardware and its software stack.
YouTuber TechGeek Tesla decided to try out how quickly Tesla's vehicles react when they simulate a person walking in front of the car. Given how vocal Tesla is about the upgraded hardware and software that it puts into the car, it made sense to see if either affected how safe the car really is (at least in the pedestrian-crossing-the-road test).
