"On the Limit" Achievement Route.

"On the Limit" Achievement Route. Started above ChazCar Derby at the fork in the road, charge down Boost briefly (tap boost, don't hold longer then 1 or 2 seconds) to push Raptor & increase it's gear changes faster, unlocked Achievement about half-way down just driving as straight as possible to the Player position. Player position is where I flew off the Map! Jumping off a ramp & over a Bandit Den LMAO.

Seen better videos (compared to one shared) of this being achieved on Dune Sea from the Wetlands past Ranger & Sentry or on the Broken Tract near Gunbarrel & Mutant Bash TV but found keeping a straight line at either next to impossible & being so far into the game finally getting this, Convoys, Racers & Authority Tanks would be constantly in the way elsewhere on the map. If your going for this it's best done after unlocking the Raptor as early as possible by clearing out enemy Fuel Depots, Road Blocks or Choke-points, retaking Immortal Shrouded Power Stations, destroying Convoys & Authority Sentries for Loosum Hagar's Projects & reach Level 10. (some of the lower level Sentries can be easily destroyed with the Phoenix's Gatling Guns, your Assault Rifle, Firestorm Revolver (on Overdrive) & Rocket Launcher.

*Once you get the Hyper-Cannon, Pulse Charge Cannon, Feltrite Laser Cannon (Rise of The Ghosts DLC Weapon) all which can destroy any Sentry very quickly (even before global damage buffs are added) you'll probably already have the Raptor by then or you could just use the BFG-9000 (which you find at the start of the game if you have bought it or the Deluxe Edition of Rage 2, best version to get as you'll get Rise of The Ghosts DLC which is the only other DLC worth unlocking behind a paywall) to destroy them very quickly but I'd save the BFG Ammo for Abadon Crushers or Sentries around Level 7+ in difficulty.

I'd also recommend going for this Achievement without progressing into the 2nd or 3rd stages of any of the main Story Missions (no Authority Tanks, less heavy Authority Troopers in the way) so unlock each of the Dagger Project's bonuses for beating their primary mission by all means, just be aware that the roads will start getting more crowded as you start the next main missions.
