Hasta La Motion!

I don’t do much 3D modeling /animations however, I have just finished a Car chase sequence in Maya. I plan on doing the motion blurs & Lens flares in Nuke. although I have the motion blur covered already, I keep telling myself "there must be a better way" when it comes to the lens Flare.

I need to track the headlights of the car and then apply the lens flare.

So when in nuke, I tracked the headlamps. But I keep thinking there might be something better I can do in Maya that will eliminate the 2D TRACKING in NUKE.
I mean, i have so much available to me in Maya (Zdepth, vector blurs,Passes, etc) So I keep thinking that I’m missing something when it comes to Tracking objects.

2d tracking in Nuke? Is this the only way?

Thanks,
