On yesterday's investor call, Peter Rawlinson gave a tiny update on the Gravity.
He didn't explicitly say it, but the "first half of 2024" would be a delay compared to what they were promising just a few months ago: Lucid Gravity on track for 2023 release
This makes sense given that they also used yesterday's call to announce they'd be building significantly fewer Airs this year than they had planned, which they blame on the chip shortage. If they're having trouble getting the silicon they need for a car they already have supply contracts for, I can believe they'd need to be more conservative for the Gravity.
Still disappointing though.
