Part 3/6:
A significant part of the discussion describes how passing vehicles, particularly trucks, cause the iPad’s readings to fluctuate wildly. The speaker mentions that larger vehicles tend to make the device “go wacky,” indicating that the device picks up strong magnetic interference, likely from the metal structures within vehicles or magnetic fields generated by their engines and electrical systems.
Such fluctuations can be tedious or entertaining, depending on the user's perspective. For demonstration, the speaker waits for a truck to pass by to observe the effect, highlighting how the device responds dynamically to real-world stimuli.
