idk. we do the regular nod too though, so people will understand you if you nod/shake your head like you would anywhere else, people will still understand. we just do both interchangeably. also there's subtle difference
our "nod" for denial starts with an upward motion of the head, while the nod for affirmation starts with a downward motion.
and the head shake for affirmation isn't a horizontal headshake from side to side like the one for denial, it's more like moving your head like a metronome.
nobody gets this. it's not just the same motions but with opposite meaning.
not always, just most of the time.
can't help but feel it would be giga based to cruise around in one of these cars. still considering it?
