The idiots with dynos ruined a lot of engines and transmissions before.
We use dyno emissions inspection systems here and I have never heard of any engines or transmissions getting ruined.

And when the OEMs know that they aren't going to be checked up on year after year, what will happen to the quality of the installed components ?
Surely a ECU can be programed to not allow normal operation of a vehicle if emmisions paramiters are out of a margin. This would pretty much require corrections to take place with out big brother.

Thank goodness there were fewer cars on the road back then... or even just parked in driveways...

This doesn't account for tampering. It's a small percentage, but every once in a while I see a "tuner car" that's running so rich that the bumper above the [censored] can is black.
