There are times when knowledge of physical devices can puzzle one's friends, however my familiarity with progress in auto equipment, and in this case with criminal assaults on them, comes legitimately from membership since 1961 in SAE - a principal "Standards Organization" for automotive (and other transport related) vehicle design and construction.
With nearly 50 years of watching the "corporate criminals" fairly closely, one picks up significant bits of what the other ones are into.
Having children who actually believe the friends who say "I can fix your car for you real cheap" adds a bit of peripheral spice to the learning, since one gets into the details by repairing lots of "repairs."
