The only acceleration needed as one of the completion scenarios is to accelerate to 20-30 MPH and maintain steady speed for 4 minutes...then find a stretch of road where you can accelerate from 40-60 MPH & maintain a steady speed for 15 minutes. Neither of those would be considered "racing speeds" unless you're driving through a school zone.
You don't have to do all of them right in a row...you just need to perform what is required (on the top half of the chart) for the time and speed given. The 1st and last requirements (cold idling for 3 minutes & warm idling for 5 minute IN GEAR (not park)) also need to be performed.
Good luck.
