G-99 Breakneck.

The G-99 Breakneck is awarded to players in  [80] License Not Required, part of the second chapter of the Undermine(d) campaign. This is technically not a mount, but a customizable D.R.I.V.E. vehicle, and only works in Undermine. D.R.I.V.E., or Dynamic and Revolutionary Improvements to Vehicular Experiences, is an experiment and iteration of ground mounts in the same vein of the transition from Steady Flight to Skyriding.

Summoning macro

Since the G-99 isn't a mount, the [Summon Random Favorite Mount] button won't put players on it. Consider using a macro like this, which will summon the G-99 in Undermine and use a random mount elsewhere. Hit the macro again to dismount.

Mechanics

In addition to a significantly higher top speed than ground mounts (approaching that of skyriding), the G-99 has two major mechanics, boosting and drifting. Players can expend turbo meter for a brief but significant boost to their speed. The turbo meter does not refill on its own but instead is topped up by running over Kaja'Cola cans or drifting around corners.

Drift by turning, then press and hold Space. The longer the drift is held, the more turbo meter will refill. Do not hit Space before starting a turn, or the G-99 will jump like any other mount.

Customization

D.R.I.V.E. customization

Main article: Shipping and Handling

While in the vehicle, players can hit the  [Caddy Caller] (also as the #5 ability) to start taking Shipping and Handling jobs for a small reward of [Valorstones] and [Resonance Crystals]. Complete a streak of ten jobs without stopping to earn bonus rewards, including a chance at the  [Violet Goblin Shredder] mount at or above Renown 8 with the Cartels of Undermine.

Every hour at the bottom of the hour (xx:30), the Surge Pricing event runs for 15 minutes. Work alongside other players on the realm for double rewards and chests containing more Valorstones, Resonance Crystals, Crests, and gold.
