driving the "drive cycle"
 

My 2001 Sonata GLS didn't pass the emission test. The test result says that O2 sensor and Catalyst are "Not Ready."
I took it to a dealershop, and they replaced the parts and fixed it. They cleared the codes but still they are not ready.
The mechanics at a dealershop keep saying that they've fixed all the problems and that there is nothing I can do but running... So I ran. I ran more than 600 miles and went back to the dealershop every morning in vain.
Recently, I found the "drive cycle" and heard that one man from California did drive exactly as was instructed by the drive cycle manual.
I believe that it'll be somewhat dangerous to drive that way. So, I'm thinking about "driving" my car with the front wheels lifted up. Then I can "run" without moving my car. Will this idea work? Is there any other thing that I should take into consider?

I don't think putting the car up on a lift and performing the "drive cycle" will work, as it must be performed under "load" conditions. Better to drive around with the help of an assistant (who can read the schedule and time the actions, etc.)
