and run the car in gear/D at "speed" with the wheels turning? For a FWD car, the front end would be on jack stands.
Has anybody gotten the drive cycle to run and the monitors ready by doing that?

I feel like if that was an option, dealerships would do it. When I had a bunch of emissions related engine work done on my BMW, they had to take it on extended test drives in order to see if the engine lights would come back on. Your ESC and traction control will probably go nuts.

Here is one good reason why that is a bad idea:

The car in question is an older car with no ESC or traction control.

Then I think theoretically it should work. Set the cruise control and step away. This is highly dangerous btw.

Unlikely. It needs to see the 02s operating through the full response range, including acceleration under load and sustained decel (ie 60-20 in top gear, no brakes). It also may not get enough heat in the Cat to set its monitor without the engine under load. More often than not, I can get a car to set most, if not all monitors on 1 road test with 2 key cycles from cold, but I'm in a somewhat rural area and have 2 country roads within a few miles of the shop that are lightly trafficed and enable me to drive oddly for a good distance. VW/Audi cars have a monitor set program through the scan tool that can be run in the shop, but I find it easier & more expedient to just drive them.

Very unlikely, though clever idea. The reasons I'm fairly certain it won't work are load and temperature. A dyno with a large fan should work though.
