Very much my own opinion, but this continues comma’s extremely cavalier attitude towards safety. PCIe connectors and GPUs are not vibration rated. What happens when you hit a bad pothole?
More generally, Comma's safety is handled by a microcontroller. The microcontroller limits steering torque commanded to a safe range for level 2 driver assistance and acts as a watchdog for the rest of the stack. Failure of openpilot causes it to disengage and sound an audible alarm.
