[AT] OT modern computer controlls

[Stephen Offiler]

My point, Dean, is not really pro-EPA nor con-EPA.  My point is that
computerization might have been started by emission controls, but that's
history already.  MANY aspects of modern automobiles (and modern farm
equipment for that matter) that have nothing at all to do with emissions
(antilock brakes, traction control, security systems, entertainment
systems, climate control systems, automatic transmissions, etc) are now
computerized.  Therefore, repairs that relate to any of these systems now
tends to require a level of equipment and technical understanding that
surpasses most shade-tree do-it-yourselfers.

SO
