The interesting thing is that a technical solution already exists as has been in use in Europe for decades.

Each driver has a single unique physical "driver card" which needs to be inserted into a tamper-proof recording device in the vehicle. Driving hours are recorded both on the driver card, and on the vehicle-bound recording device. Want to use two drivers in a shift? Well, you gotta put it on dual-driver mode and insert both cards. Good luck trying to explain where your ghost driver is when you get pulled over for a random check.

It seems ELD Rider is just a random Android app instead. No wonder people are committing fraud with it - there's no way to ensure the accuracy of that!
