I remember there was a suspicion about the nature of these because Tesla have chosen not to be certified by third parties for safety and only posted these in-house crash videos instead, no other data has been shared. It rose some eyebrows because Elon could has dodged the regulations just out of spite and to cut corners in time, money needed for that, but at the same time we don't know if their own tests are legit and how many of them have been done - all we see is these posts by his SMM team. This conversation about CT safety consists of only one party, Tesla, that has obvious economical interests, so you either trust them or not.
