If there is any consolation I can take with the cargo space is, if the reason for lower than assumed cargo space is because they took some real estate from the frunk and the trunk to have the best in class cabin space to accomodate all 4-5 adults with enough legroom. As Elon or one of the engineers mentioned that your are seated way forward and way rearward as possible.
Sorry for venting a bit excessively, y'all... the cargo space got me over the edge... in addition to this perpetual 'But why don't you 'just' buy an S, Mr. Russo?' selling pitch... !!
Sure I would, if I could... even the lowest battery size with minimal frills... yet then there would be no more money to pay for the divorce from my (definitively always very human) OTHER... (, @Badback !).
So, ok... trailer hitch, anyone ?
