driving a car, for me, has always been very detrimental to my sense of direction, because it's so active and stressful and there's too much to focus on, and you're quite separated from your environment. i always end up having to rely on google maps, until ive made a trip around a dozen times.
by contrast im now dependent on a bike, and i can just remember the turns to get somewhere. ive used my bike's phone holder maybe twice. if i do have a lapse in memory i can just stop and double check on maps or notes ive taken, but most of the time its just there in my head. i look up a new route on google maps at home and then i just go do it
