V shaped gradient texture - Car Livery I am working on a livery of F1 car (it's my first project after tutorials) and want to achieve a V-shaped car livery like on this photo:

I created a gradient texture with texture coordinate on an empty, like the guy in this video:
YouTube and it looks like below. The empty allows me to rotate and scale the gradient texture. I thought that since there is a Mirror modifier on the body, the shader would also be mirrored, but it's not the case. I want to mirror it, like on the screen from the video.
I tried moving, rotating and scaling the empty, but it didn't work :(

Gradient I want to achieve:
You were so nearly there... :D
At the risk of starting a game of Node Golf, if the question is: 'How do I make a procedural chevron?' ...then a minimal answer could be something like this, mirroring in X by using its Absolute value:

This assumes the origin of your model is on its mirror axis. The Map Range 'From' figures would depend on the size of your object. Both of those conditions are tweakable.
The texture is in XY, and can be projected through any model:

@brockmann: to get a rounding at the tip pf the chevron without getting too complicated, you could forget the Absolute, and select ranges from y + sqrt((x^2) +n). Here illustrated with n=0.005, n=0.001, and n=0, which returns us to the un-rounded chevron.

Blurring could be achieved by chnging the Color Ramp from 'Constant', and putting in gradients from red to white, and/or, muddling the whole texture space with some noise.
