This code-along builds a vehicle-combat highway from the real, tested @babylonjsmarket components — nine of them, plus the free arcade core. You start with the road itself: a ring of fourteen asphalt slabs that recycle around the car, so the highway never ends and the car's world Z never grows into a seven-digit float. Then you put a car on it that behaves like a car rather than a walking character — throttle along the nose, steering that washes out with speed, momentum that doesn't turn when the wheel does. Traffic streams in ahead of you out of two pooled blueprints and is handed back once it falls behind, always measured off the player's live position rather than a fixed pad. Ramming becomes a real mechanic once damage is gated on closing speed: a nudge is worth nothing, a head-on is worth plenty, and it costs the rammer too. Then the road starts fighting back — a smoke screen that blinds pursuers where you were rather than where you are, an oil slick that takes away your say without taking your speed, gravel that costs you time, a van that swallows your car and puts it down with a new weapon, and a convoy whose trailers retrace the truck's exact path round the bend instead of cutting the corner. It ends at the water, where the vehicle swaps handling, buoyancy and silhouette for a hull. Each part is a separate ECS component that talks to the others over the EventBus and never reaches into another, every code block is a verbatim slice of live source, and the scene you assemble ends equal to the library's own VehicleCombat scene.
