Many things are unique about a rolling road, like one set of wheels

That wouldn't work for me, my tester checks exhaust emissions before
hitting the rolling road.

What - he takes the vehicle out for a full speed blast on the road
connected to testing equipment?

He sets a hot engine to 2Krpm and his puter does the rest. He doesn't use
the OBD port. Then moves to the rolling road to test the brakes only. Then
steering linkages, suspension springs, brake pipes, etc. Bulbs.
That's it
