Drive rush….

I’m relatively new to street fighter, played street fighter 2 as a kid and pretty much just mashed buttons, so i don’t really understand a lot of the mechanics from past games that they have implemented into 6. I play on Xbox with the pad and have made it too gold 4 as zangief, when I did the tutorials i remember it saying after certain buttons double tap forward to drive rush, I could do it with the directional pad but not with the stick, I can’t SPD with the pad, only stick. So I gave up on using drive rushes. Today I found out I can drive rushed using left trigger after certain inputs. I feel really really REALLY stupid, I’m sorry for this pointless information , but I just wanted to share.
