I found a number of different drive cycle procedures on the Internet. I've tried a few of them. This one (attached image) seems to be the most official one. What's not clear to me are the followings...

1. Is cold start necessary? If yes, that means if a drive cycle is unsuccessful, you'll have to wait a few hours to try again.

2. Do the four phases need to be continuous? It's very difficult to find a stretch of road where you can drive 20-30 mph for 3 minutes 15 seconds and immediately accelerate to 40-60 mph and maintain for 15 minutes. I live two miles from the nearest stretch of open road. If that's a requirement, it's almost necessary to complete the drive cycle on a dyno.

3. Can cruise control be used to maintain 40-60 mph?
