I honestly took it to mean that when he took his car into service, Lucid gave him a loaner car (through Hertz, as usual) and that car happened to have CarPlay (as most rental cars do nowadays.)
"Loaner Lucid gave me has CarPlay."
He never said Lucid gave him an Air as a loaner. Seems pretty straightforward to me.
When he says "Lucid finally gave me CarPlay" he meant it as a joke. A bit of irony. Nothing more.
I'm surprised others seem to be reading it differently.
