thank you for pointing this out and I've been meaning to make a post about this as well.
yes you can do the small pushes by tapping but I've always loved the aesthetic and act of pushing between tricks, it looks realistic and for clips it fills in those dead zones vs just standing on your board in between obstacles in a line.
in season 1 it felt good and looked better, ,your character when doing hard pushes looked like he was really emphasizing the push to gain speed but with season 2 they removed that animation and with every season they increase the speed in every aspect not just push speed for example transition speed. cruising speed (takes longer to slow down), trick speed, we actually gain speed when doing tricks and that makes zero sense. landing speed, we often lose zero speed even landing even on flat and sometimes even gain speed which also makes zero sense..
when you add all those together as a realistic player I'm constantly trying to slow down because I'm going to fast. if I want to go fast I should have to work for it but the game just gives it to me regardless.
