alt Hacker NewsI see little need to speculate here.
The obvious explanation would be that this design for the roadster took 8 years to come to fruition for a demo-able prototype.
I also very much doubt the 2028 timeline for delivery, and what the purpose of the Rocket edition is. Perhaps it's just a prestige project.
The non-flying version at least seems usable on a racing track.
The speculation is because it’s such an absurd thing to demo or even aspire to. Nobody wants or needs this. So why do it?
I guess the answer is because it was Musk’s whim and nobody dared say no, which doesn’t bode well for Tesla.
