I have a ‘premium’ magnetic phone holder just above my # 2 vent which has only dropped the phone a couple times over RR tracks. In those cases it dropped straight down. A few days ago I barreled into an exit ramp that had a little speed bump a short ways in. The phone fell off and traveled to about 8 o’clock and on the way hit the fob and shut the truck off. All of a sudden the gauges are at zero, the truck is quiet as hell and the steering is a little stiff. It took me about 3 seconds to realize what happened and I restarted it. The kind of thing that never would have happened 20 years ago with ignition on the column and no cell phone.
