I don't know much about law enforcement and tactical driving, but I do know a bit about racing and losing control of vehicles at high speed. I'm not sure what other action here would have caused the suspect vehicle to:
1. Move right, rather than across traffic.
2. Move right now rather than when the oncoming traffic is nearby.
The only other thing I see here would have required overtaking on the left, which I don't know that the officer had time to do.
