HOW IT WORKS
1. Get Nitro Item - Player obtains "nitro" item from inventory
2. Command - Use /nitro command near vehicle
3. Installation - Stand near engine, press E to install
4. Wait - 5-second installation animation plays
5. Activate - Hold Left Shift while driving to boost
6. Depletion - Nitro percentage decreases during use
7. Empty - System stops when nitro reaches 0%
