[AT] OT modern computer controlls

[Dean VP]

Stephen,

The EPA has done some good things to help clean up the air but IMHO have
gone way overboard in over regulating causing excessive cost increases for
manufactures.  There has to be some kind of reasonable balance.   We are not
at that point right now.

It's better to be judged by 12 than carried by 6.

I don't intended to sound like I'm disagreeing with Thomas.  I think his EPA
comment does in fact apply to the basic history of modern engine complexity.
But as usual the story is a lot more complex than that.  I lifted the
following from Wikipedia because I agree and so it saves me a bunch of time
trying to summarize what I know about Right To Repair legislation and
controversy (I work in the automotive aftermarket, and occasionally some of
this stuff touches me professionally)

"...The 1990 Clean Air Act Amendments required all vehicles built after
1994 to include on-board computer systems to monitor vehicle emissions. The
bill also required automakers to provide independent repairers the same
emissions service information as provided to franchised new car dealers.
California further passed legislation requiring that all emissions related
service information and tools be made available to independent shops.
Unlike the Clean Air Act, the California bill also required the car
companies to maintain web sites which contained all of their service
information and which was accessible on a subscription basis to repair shops
and car owners.

As automotive technology advanced, computers came to control the vital
systems of every vehicle, including brakes, ignition keys, air bags,
steering mechanisms and more.[3] Repairing motor vehicles became a high-tech
operation, with computer diagnostic tools replacing a mechanic's observation
and experience.[4] These developments eventually made manufacturers the
"gatekeepers" of advanced information necessary to repair or supply parts to
motor vehicles..."
