I don’t know if it’s universally true, but my cheap li’l cell phone logs the time and date of incoming/outgoing calls and texts. Defense Exhibit A, your honor...
FYI - I experienced an accident in 1997 where I was driving along Highway 101 in CA during a heavy rainstorm. A large rock rolled down the hill directly in my path and I wasn't able to avoid colliding with it. The damage to my vehicle was extensive (took out the transmission and steering). A CA Highway Patrolman drove by within minutes of the accident. I explained what happened. He wrote up an accident report and submitted it to DMV. They took a point from my license, apparently claiming that I was "distracted" and didn't see the rock - I have no idea what the "LEO" wrote in that report, but I wasn't distracted. As there was no impact upon my license or insurance, I didn't contest this. But, I think you get my point.
