Not say I agree but here is the logic. Self closing trunks are pretty common on many vehicles. A problem that is/was (I think a lot of manufacturers have mostly fix it) happen was the trunk lid would detect the resistance from a grocery bag or something. You know the stuff that in the past you could have just shut the lid with a little force. When this resistance was felt the lid would open back up. A good thing for safety but it can lead to the trunk never closing.
I bet when Tesla wrote the code they forgot to give it a maximum pressure it could close with regardless of how many times it closed. Or they set the maximum pressure way too hard.
