HERE IS A 2018 MODEL X IN THE JUNKYARD. HTTPS://WWW.COPART.COM/LOT/61359249/PHOTOS THE FRONT OF IT IS BADLY SMASHED IN AND ALL OF THE FRONT END DAMAGE CAN BE EXPLAINED AS BEING THE RESULT OF THE CRASH. BUT! WHY IS THE BACK WHEEL WHOMPY? IT IS HIGHLY LIKELY THAT THE BACK WHEEL GOING SPONTANEOUSLY WHOMPY CAUSED THE CRASH. SURELY THIS IS BLINDINGLY OBVIOUS. PLEASE INVESTIGATE THANK YOU. KEEF
