Somebody wanted to tell you. The 1-800 made sure they didn't.
A parent watches one of your vans blow through a crosswalk near a school at pickup time. She's furious, and she wants to say something. She catches the unit number and, on the back door, a faded sticker with a 1-800 and a five-digit code.
She's driving. She's not dialling a toll-free number and reciting a code from memory at the next light. By the time she's home she's cooled off, or forgotten the number, or decided it's not worth sitting through hold music to leave a message she suspects nobody checks.
So the one report that might have started a coaching conversation never reaches you.
And on the days it goes the other way — a driver who stopped to help, who waved someone in, who was a credit to your name — that never reaches you either. The good and the bad both die at the same dead number.
The observation isn't the problem. People see your vehicles all day. The problem is that the only channel you offer is one nobody will use. NotifyMeDriving replaces it with the thing already in the witness's hand: a phone camera, a QR code, and about a minute.
