Got my first used tesla m3 today

traded in my first car for a used 2023 one. My mazda will be missed... but I drove on the highway after and with the driving set to HOLD mode, it felt really weird on the highway at some point in my feet. It felt like at some point like my foot didn't feel the "gas/accelerator" pedal since I have to rest my foot on there the entire time. Unlike my gas car where you'd remove the foot off pedal often to let it coast/crawl... and use break a lot. It felt like my foot was getting tense and tired... numb LOL. Maaybe even felt like I was losing my positioning of the pedal. Dangerous. I felt like I couldnt control it too well at some point because it felt like my shoes were slipping a little. Plus with interior being all black (well it was day time) i couldnt see the pedals to reposition.

I was thinking maybe I need to change the pedals to those metal ones with the rubber on them? Im so used to my cx30 seating position so i have to get used to this... I set it to roll and driving feeeels so much better but heard it will literally be potentially dangerous if going up hillls....

So i wanted to try crawl but idk everyone tells me learn HOLD
