Here’s an example of a bug in an embedded system (a dive computer for use in Scuba) that might have killed http://www.cpsc.gov/cpscpub/prerel/prhtml06/06194.html
The design of bridges and roads and the engineers who work on them are regulated by states and the federal government. The modern equivalent of bridges and roads are often embedded computers, but there is little regulation outside of medical devices (FDA) and avionics (FAA). Sooner or later, this unregulated posture may get us into big trouble as a society.
