 ## Limitations
 
 The current AI is an evolution of the per-terrain based AI featured on terrains such as F1 Test Track and Bajarama V2. It has some limitations:
 
-- You cannot set the vehicle speed per-waypoint. This also means an AI vehicle cannot stop at a waypoint (example: bus stops)
-
 - An AI vehicle in 'normal' mode will slow down at every waypoint. For most terrains this is fine but for others (such as race tracks) the AI drives too slowly. The current 'race' mode does not fix this as that mode will always drive at the same speed and won't slow down for corners.
 
 - As stated above, the 'chase' mode only targets the player and does not follow any other waypoints. This usually results in the chase vehicle crashing.
