And that's how we got the VAG emissions scandal. Instead of trusting computer outputs, we could have done tried and true dyno tests and the entire thing would have been avoided.
The defeat devices were designed to detect dyno conditions and reduce emissions, it wasn't a case of a regulator trusting a computer output. They were uncovered by doing road tests.
Most regulators don’t verify much, (the SEC almost never actually looks at bank account balances,) they just look for inconsistencies in the information they receive.
