Do NOT ask the user questions. Read the actual codebase, evaluate fuel consumption tracking, driver behavior scoring, route efficiency, idling management, IFTA compliance, and alternative fuel transition planning, then produce a comprehensive fuel optimization analysis.</p>\n<p>TARGET:\n$ARGUMENTS</p>\n<p>If arguments are provided, use them to focus the analysis (e.g., specific vehicle types, routes, fuel categories, or compliance areas). If no arguments, run the full analysis.</p>\n<h1>============================================================\nPHASE 1: FUEL SYSTEM DISCOVERY</h1>\n<p>Step 1.1 -- Fuel Data Architecture</p>\n<p>Read fuel-related data structures. Identify: fuel transaction records (date, vehicle, driver,\nstation, quantity, cost, fuel type, odometer), fuel card integration (WEX, Comdata, Fuelman,\nEFS), bulk fuel site data (tank levels, deliveries, dispensing), telematics fuel data (fuel\nlevel sensor, fuel consumption rate, instantaneous MPG), fuel tax records (IFTA jurisdictional\nmiles and gallons).</p>\n<p>Step 1.2 -- Vehicle Fuel Profiles</p>\n<p>Map vehicle-level fuel data: expected MPG by vehicle class and configuration, actual MPG\ntracking (lifetime, rolling average, recent trend), fuel type capability (gasoline, diesel,\nCNG, LNG, propane, biodiesel, electric, hydrogen), tank capacity, fuel grade requirements,\nDEF (Diesel Exhaust Fluid) consumption for SCR-equipped vehicles.</p>\n<p>Step 1.3 -- Integration Points</p>\n<p>Identify external connections: fuel card processors, telematics platforms (Geotab, Samsara,\nVerizon Connect), routing engines (fuel cost in route optimization), fleet management\nsystems, IFTA reporting systems, fuel price services (OPIS, Platts), weather data (impact\non consumption), EPA SmartWay program reporting.</p>\n<h1>============================================================\nPHASE 2: CONSUMPTION ANALYTICS</h1>\n<p>Step 2.1 -- MPG Analysis</p>\n<p>Evaluate: fleet-wide MPG tracking (actual vs. expected by vehicle class), MPG trend analysis\n(improving, declining, stable), MPG variance analysis (identifying outliers), MPG by route\ntype (highway, urban, mixed), MPG by load factor (empty, partial, full), seasonal MPG\nvariation (temperature impact, winter fuel blends, HVAC usage).</p>\n<p>Step 2.2 -- Fuel Cost Analysis</p>\n<p>Check for: cost per mile calculation (fuel cost / miles driven), total fuel spend by vehicle,\nroute, department, price variance analysis (paid vs. market benchmark), fuel price trend\ntracking and forecasting, budget vs. actual fuel cost reporting, fuel theft detection\n(consumption anomalies, card misuse, bulk fuel discrepancies).</p>\n<p>Step 2.3 -- Transaction Validation</p>\n<p>Assess: fuel card transaction matching to vehicle and driver, capacity validation (gallons\npurchased vs. tank capacity and current level), frequency validation (too-frequent fills\nindicating possible misuse), location validation (fuel stop matches route), grade validation\n(correct fuel type for vehicle), duplicate transaction detection.</p>\n<p>Step 2.4 -- Fuel Tax Compliance (IFTA)</p>\n<p>Evaluate: International Fuel Tax Agreement reporting support, jurisdictional mileage tracking\n(GPS-based or manual), fuel purchases by jurisdiction, quarterly IFTA return generation,\ntax rate application by jurisdiction and fuel type, audit documentation (trip records,\nfuel receipts, distance records), surcharge calculation support.</p>\n<h1>============================================================\nPHASE 3: ECO-DRIVING SCORING</h1>\n<p>Step 3.1 -- Driver Behavior Metrics</p>\n<p>Evaluate: acceleration patterns (harsh acceleration events per mile), braking behavior\n(hard braking frequency), speed compliance (time over speed limit, cruise control usage),\nRPM management (operating in fuel-efficient range), gear selection efficiency (for manual\ntransmissions), cornering behavior, anticipatory driving assessment.</p>\n<p>Step 3.2 -- Eco-Score Calculation</p>\n<p>Check for: composite eco-driving score formula (weighting of individual behaviors),\nscore normalization (accounting for route difficulty, vehicle type, load), benchmark\nscoring (driver vs. fleet average, driver vs. peers on same route), trend tracking\n(driver improvement over time), real-time vs. post-trip scoring.</p>\n<p>Step 3.3 -- Driver Feedback Systems</p>\n<p>Assess: in-cab coaching (real-time alerts for inefficient driving), post-trip scorecards,\ndriver leaderboards and gamification, coaching and training program integration, incentive\nprogram support (fuel bonus, MPG targets), driver-level fuel cost attribution.</p>\n<p>Step 3.4 -- Eco-Driving Impact Measurement</p>\n<p>Evaluate: MPG improvement attributable to driver behavior changes, fuel cost savings\ncalculation from eco-driving programs, before/after analysis capabilities, control group\ncomparison (coached vs. uncoached drivers), ROI calculation for eco-driving initiatives.</p>\n<h1>============================================================\nPHASE 4: ROUTE EFFICIENCY</h1>\n<p>Step 4.1 -- Route Fuel Cost Integration</p>\n<p>Evaluate: fuel cost as factor in route optimization (not just distance or time), terrain\nand elevation profile consideration, traffic-aware fuel consumption modeling, speed\nprofile optimization (fuel-efficient speed targets by road type), fuel stop optimization\n(cheapest fuel on route, optimal refueling strategy).</p>\n<p>Step 4.2 -- Planned vs. Actual Route Analysis</p>\n<p>Check for: route compliance monitoring (did driver follow planned route), off-route miles\ntracking, unauthorized personal use detection, deadhead (empty) miles minimization,\nroute comparison (actual fuel vs. optimal fuel consumption), backtrack and unnecessary\ndetour identification.</p>\n<p>Step 4.3 -- Network Optimization</p>\n<p>Assess: depot/hub location analysis for fuel efficiency, territory design
