About Vững Lái: Following Distance
Vững Lái (Vung Lai) is a following-distance assistant that runs entirely on your iPhone. Mount the phone sideways on the windshield: the rear camera and on-device AI spot the vehicle ahead in your lane, estimate the distance, compare it with your GPS speed and warn you when you follow too closely. THE 2-SECOND AND 3-SECOND RULE, MEASURED FOR YOU • Canada: the 2-second rule, in km/h and metres. • United States: the 3-second rule, in mph and feet. • Vietnam: Circular 38/2024/TT-BGTVT for dry roads, with a 1-second reminder from 20 km/h below its speeds. • The region is guessed from your phone and can be changed in Settings. ALERTS YOU DON'T HAVE TO LOOK AT • Under the safe distance: the gap card turns amber, and is spoken once it lasts a few seconds. • Really close (under 3/4 of the safe distance): red, sounded at once. • Tones, vibration and voice prompts in English or Vietnamese. • Warning when the gap closes fast: "Careful ahead!". • Stop sign and pedestrian reminders. • Three sensitivity levels: Calm, Balanced, Sensitive. DRIVER ASSISTANCE ON THE PHONE YOU ALREADY HAVE • No extra hardware: a windshield mount is all you need. • Calibrates its camera by itself in the first minutes of driving and remembers the mount. • Scales back its work when the phone gets hot, to keep running smoothly. PRIVACY • Camera images and location are processed on the phone, never recorded or uploaded. • No account, no ads, no tracking. The app collects no data. SAFETY NOTICE Vững Lái is an as
