Car Rush

🏎️ Optical Flow and Vanishing Points

Car Rush is a study in linear perspective and optical flow. Unlike simulation racers that focus on complex tire physics, this title focuses on the visual processing of speed. The game uses a forced perspective camera angle (low and behind) to exaggerate the parallax effect—objects in the foreground move significantly faster than the background, creating a heightened sensation of velocity known as "vection."

The aesthetic is "Low Poly," reducing visual noise (texture aliasing) to allow the player to focus entirely on the geometry of the road. This makes it an excellent test of reaction time and predictive tracking without the cognitive overhead of photorealistic distractions.

🧠 Depth Perception Training

The gameplay loop exercises specific visual cortices:

• Vanishing Point Tracking: The road curves generate a constantly shifting vanishing point. The player must fixate their gaze on the horizon to predict turn severity before the car arrives at the apex.
• Size Constancy: Obstacles (other cars) grow in size as they approach. The brain must calculate the "Time-to-Collision" (TTC) based on the rate of retinal expansion (Tau theory).

🎮 Mechanics: Arcade Physics

The control scheme favors accessibility over realism:

• Infinite Grip: The car does not drift or slide. Lateral movement is instantaneous and linear. This shifts the difficulty from car handling to pure obstacle avoidance.
• Time Extension: Checkpoints provide time bonuses. The game is not a race against opponents, but a race against a decaying timer (entropy), requiring near-perfect racing lines to sustain the session.

🏆 High-Speed Strategies

1. The "Horizon Gaze" Technique

Novice players look at their car. Expert players look at the top 20% of the screen. By focusing on the furthest visible point of the road, you gain approximately 1.5 seconds of extra reaction time compared to looking at the bumper.

2. Micro-Adjustments

Do not hold the steering key. Use rapid, short taps. This keeps the car centered in the lane and prevents over-correcting into off-road barriers, which carry a heavy deceleration penalty.

🛡️ Technical Performance

Engine notes:

• Draw Distance: The engine uses aggressive Level of Detail (LOD) culling, ensuring that the frame rate remains locked at 60fps even on mobile browsers, which is critical for the sense of speed.
