Wheelchair enables vehicles to drive around on [[Collision types|solid out of bounds (OOB)]], as OOB detection on this collision checks that your wheels are on or very near to the ground. Wheelchair with Tiny Titan/Classic Dragster has been used in [[Koopa Cape#Unrestricted Flap|Koopa Cape UR Flap]], [[DS Desert Hills#Unrestricted Flap|DS Desert Hills UR Flap]], and [[DS Peach Gardens#Unrestricted Flap|DS Peach Gardens UR Flap]] to navigate around checkpoints while driving on solid OOB. Wheelchair with Dolphin Dasher is part of the theorized optimal strategy for DS Peach Gardens UR Flap for the same reason.

==== ~~Speed redirection~~ ====

==== Headsliding ====

~~While IV is limited~~ in wheelchair~~, vehicles can~~ gain [[External velocity|EV]] from slopes because the body hitboxes do not have traction with the ground. ~~Separately~~, when a vehicle flips out of wheelchair, its direction of movement will flip along with it. ~~These two factors together allow~~ a vehicle to redirect instantaneously from moving quickly backwards to moving quickly forwards. This is the optimal strategy ~~for~~ [[DS Yoshi Falls#No Ultra Flap|DS Yoshi Falls NU Flap]] to enter the finish line backwards from the front (after a DLC) and then immediately start traveling forwards.

Vehicles in wheelchair gain [[External velocity|EV]] from slopes because the wheels are not touching the ground and the body hitboxes do not have traction with the ground (see: [[Supersliding#Headsliding, cranium sliding, whatever (name pending)|Supersliding]]).

Notably, when a vehicle flips out of wheelchair, its direction of movement will flip along with it. When used with headsliding, this allows a vehicle to redirect instantaneously from moving quickly backwards to moving quickly forwards. This is the optimal strategy on [[DS Yoshi Falls#No Ultra Flap|DS Yoshi Falls NU Flap]] to enter the finish line backwards from the front (after a DLC) and then immediately start traveling forwards.

=== Extended HWG ===

Colliding with a barrel roll wall sets the "HWG timer" to 10 frames, during which barrel roll can be activated. This timer is so-named because it is also responsible for activating [[horizontal wall glitch]] (HWG). HWG usually ~~lasts for~~ 20 frames, but ~~in certain cases~~, HWG will continue so long as the timer does not count down to 0. This can be exploited by riding a barrel roll wall so that the HWG timer continually resets to 10, thus extending the initial HWG. This is used on [[N64 DK's Jungle Parkway#Unrestricted Flap|N64 DK's Jungle Parkway UR Flap]] to reach the seam to the left of the finish line.
