It's not a safe action. But it's also not safe to do nothing. I think the driver made the right call (and with the benefit of hindsight it was in this case.) Doing nothing would have resulted in a high speed accident with certainty of 1. This could have involved a head on or left wreckage on the highway. The driver took a chance on a risky intervention and it paid off.
