What should I have done

I was on my normal ride home last night and came to a 2 lane junction with lights. The left lane was for traffic going straight across and the right lane for traffic turning right. Just before this is a left turn to travel up another road to get to a hotel, this has a keep clear box. I was filtering past the line of traffic that had built up there traveling slowly to ensure nothing was going to suddenly pull out, it was all clear. Turned my head back to pull up to the lights, and what do I see the glare of head lights and a 4x4 thing swinging right in front of me! Shat my load and slammed on the brakes getting a bit of a wobble as I try to find my footing and swear under my breath. But shrugged it off and carry on home, resisting the urge that comes over me to go back down the road and follow the 4x4 down the road to have it out with the drive. As I know the road is a dead end street.
So what should I have done....

• Carried on home like I did, learning a important fact. Twats may come at you from any direction?
• Or should I have followed them down the road and had it out with the drive and maybe thumped them?
• Or... your suggestion...
