Yes, best advice is to get away from it when you can. I see forms of it every day.
I witnessed a 'good' example of escalating road rage earlier this week, 6:30am on my commute to work in my car on a 2 lane freeway ...
A couple white males, each alone in their SUV, got all ragey with each other immediately in font of me. The slower one of the two (doing ~65mph) pulled in front of the faster one (doing ~70 mph) to pass a slow semi, and then the incident started, first escalated by the ~70 mph driver that had to slow down. There were no offramps, so the incident escalated for over the next couple miles they got close to yell and finger salute, then crowding the other in the same lane, then swerving at each other, and then turning it into a daring game of accelerating and swerving in front of each other while braking hard. I and others kept slowing down, giving them space, trapped behind them. After exchanging many such aggressive, spontaneous maneuvers, one pulled over and braked at full power onto the shoulder as if inviting a physical confrontation. The other driver braked hard and stopped beside the first car (stopping in a travel lane). A moment later the one stopped in the travel lane took off and sped down the freeway at high speed (which was then empty for 1+ miles ahead) while the other thankfully stayed on the shoulder.
I thought I was going to witness an impact or a rollover, and when they stopped beside each other I thought I'd witness a fistfight or perhaps gunfire. It was apparent very quickly they were oblivious to the other vehicles on the road--there were insanely focused solely on each other.
I was not thinking about taking their license plate numbers and was more concerned about staying safe from them and other traffic behind me.
Later I started wondering ... what if I were on my motorcycle?? Obviously more maneuverable, with more acceleration and better braking ... those would be my friends in dire situations. But better yet is to actively avoid them: don't be the cause, don't escalate them (be submissive and given them space), and actively flee them when possible.
