The falcon wing doors are by far the #1 reason my parents want to replace their X with an S. The doors open to inconsistent heights (they almost never open fully) and are therefore constantly causing bumped heads. They like higher ride, higher seats, bigger cargo space, but hate the "flashy, frustrating, and painful" falcon wings so much another x is off the table.
Put normal doors on the X: save a ton of money on motors, sensors, finnicky assembly alignment, and have a vehicle that appeals to more (or at least different) people. Heck, make falcon wings and normal doors like round and yoke. I bet my parents would pay an extra 10k for an X with normal doors (that probably cost tesla 5k less to make).
Anyway, the S is not useless - it's faster, more range, and has doors that don't try to assassinate you.
