Airport garage 'remember your level' signs are useless — 1 in 5 travelers can't find their car

Airport parking garages spanning 5-8 levels with 3,000+ spaces rely on painted level numbers and 'remember your spot' signs, but travelers who park at 4am for a red-eye and return exhausted five days later genuinely cannot recall whether they parked on level 3 or level 5, section B or D. The average time spent searching for a car in an airport garage is 8-12 minutes, but outlier cases stretch to 45+ minutes, with travelers dragging luggage through diesel-fume-filled corridors pressing their key fob repeatedly. Some airports offer 'find my car' kiosks tied to license plate cameras, but these systems cover only 60-70% of spaces and frequently return 'vehicle not found.' The problem persists because garage operators optimize for maximum capacity (revenue per square foot) rather than wayfinding, and retrofitting a full ALPR-based car locator system costs $500K-1M per facility with no direct revenue uplift.
