Read a news piece about GPS sending people onto closed roads all the time. It explained how the maps don't get updated fast enough after construction or accidents. Like what @jordan_webb said, there's no check for stuff like bridge heights or weight limits. Honestly, it's scary how much we trust these systems without double-checking the route ourselves. Tbh, I heard about a delivery truck getting stuck because the GPS ignored a 'no trucks' sign. Ngl, we need better data in these apps, or people could get really hurt.

When you say 'one missed step', it's wild how small oversights add up. Like @sarahkim said about that one nut on a Piper, a single loose bolt can wreck a whole system. I remember reading about a missing cotter pin that made a plane's flap jam. How often do mechanics actually spot these things before they become a problem? Is there a good system to catch them, or does it come down to luck?
