I noticed that after returning the taxi drivers head, while running over if you jump onto and then jump off of the edge of the paths you see along the way (the part that slopes down) you get a small speed boost that pushes you forward

cant get a video but i noticed no one has seen this yet

Hi!! Thanks for sharing! This is a tech that we know about but is somewhat difficult to perform consistently. In the world record by citruslvr she performs this trick on the first slope after leaving the cave!
