[Gay State Conservative]

Mr. Hood came to realize that G.M., and the supplier that made the part, Delphi, had quietly changed the switch sometime in 2006 or early 2007, making it less likely that an unsuspecting driver could bump the ignition key and cause the car to cut off engine power and deactivate its air bags.

Does GM have to design and build each and every one of it's parts to withstand a "bump".One wouldn't ordinarily anticipate an "out-of-the-way" item like an ignition switch to be bumped...particularly while the car's in motion.Imagine what commercial aviation would be like today if Boeing and Airbus had to design *all* of their parts to withstand an encounter with a flock of Canadian geese.

an "out-of-the-way" item like an ignition switch

With all the stalk-mounted controls on the steering column, the ignition key isn't that out of the way. I don't know about this GM car, but in my toyota, when reaching for the cruise control with a gloved hand I can jangle the keys.
