Over the past months I have been doing a 100% RetroAchievements playthrough of NFS Most Wanted. Most of it was streamed live on my channel. Here you can see me getting the final 8 achievements.

Timeline:
0:00 Tesla Autopilot "Forget" to turn off Game Moment Camera
2:48 Slingshot Technique 300 MPH Photo Ticket with Lotus Elise
6:37 Screw This, I'm Going Golfing Leave track on Omega
11:37 Suggested Boundaries Leave track on NFS World Loop
15:05 Official Music Video Leave track on Seaside Interchange
20:03 Razor Never Saw It Coming Leave track on Forest Green
23:36 One Last Ride Blacklist Rank 4 Tollbooth with starter car
30:18 Juvenile Delinquency Survive 13 mins at Heat 5 with starter car

Tesla Autopilot requires you to hit a spike strip while the game moment camera is active.

For Slingshot Technique you have to use a glitch that I myself had never heard of before this playthrough. You have to upgrade the Lotus Elise with Ultimate performance parts and set all the tuning sliders in the pause menu to 3. Then you have to hold gas and brake at the same time while quickly turning left and right for a few seconds. Now when you release the gas you will quickly accelerate to extreme speed. I have added an input overlay for this achievement to make it easier to understand.

Several of these achievements require you to leave certain tracks through missing or broken barriers.

For One Last Ride and Juvenile Delinquency you have to use a stock starter car. However, the VW Golf is also treated as a starter car here, as having an Underground 2 save file will give you additional money at the start of the career, which allows you to start with the Golf.
