I cut out a car from another photograph then pasted this into the project. Give the car the same filter effects (Filter > Artistic > Poster edges) then use the Cutout filter (Filter > Artistic > Cutout) to create a cartoonish look. Play with these settings to your liking. You can find more filters under the Filter > Artistic menu.

Choose Edit > Transform > Distort then manipulate the car so that it fits on the highway lane with the correct perspective.

Don’t forget to use the Warp tool (Edit > Transform > Warp) if needed.
Add a text layer into the project and put in "VRRRROEMM". Choose Layer > Rasterize > Type then use the Transform tool (Ctrl+T or Edit > Transform) to distort the text to your liking. Go to blending options then choose gradient. (Right click on layer then choose blending options).

You can also do a black stroke around it! Here an example of the output.

I also give the car a little bit more speed by draw a line. Take the brush tool, color white, and draw a line or some lines. Go to blending options and give it a black stroke, 2 or 3px depending on your project scale. For depth do the Alt trick i explained while doing the asphalt debris and text VRRROEEMM.

I putted in another (half) car, to give a bit more action. (copy, paste from another photograph)

Make sure you tick the transform box. Scale the car to -100.

Then place the car next to the big traffic sign. Give the car also the filter effects Poster edges and then the effect Cutout, to create the cartoonish look.
