I have a weird process in tighter spots - I back into the garage where my door opens into a wall that has shit hanging from it so space is limited. I park over as far as I can to give my wife/kid as much space as possible. I don't want to slide out of the seat because I don't want to destroy the seat bolsters so when I get out of the 4runner in a tighter spot.
So here's my process that I've evolved over the months lol it all revolves around trying not to wear my seat bolsters down prematurely i.e. the chair is lava
1) Open door with left hand
2) Right hand on wheel -nicer if steering lock is engaged but not necessary
3) Left foot on side step
4) Tuck my right foot sorta under me
5) Using my right leg to give me upward force and my right hand on the steering wheel to give me forward force, I'll pull myself up and forward so my ass is off the seat and maintain a bit of a squat with my right leg. This will be the last time my ass touches the seat in the entire process.
6) I'll lean myself back such that my back will rest against the weather stripping on the b pillar; it's a dense rubber so ain't no thing.
7) With left foot providing backward force and right hand providing forward force, transition right foot on to the scuff plate. Left hand is still on the door preventing it from opening into anything. Left foot is on the side step, right foot is on the scuff plate, and back is leaning against the b pillar. Think of it as a wall-squat position -ass still not touching the seat.
8) With my back against the b pillar, my right foot bearing almost entire all my weight, and my right hand still holding onto the steering wheel for additional balance, I'll can do a controlled squat to lower my left foot onto the ground.
9) Now you're home-free and warmed up to do a bunch of squats.
