No. They are flying parallel.

Explanation

You really would have nothing to worry about. They are straight, parallel lines. This optical illusion is taking advantage of a three dimensional technique where all of the background lines meet at one point, thus making the mind see the picture as a 3D model of reality, rather than just lines on a screen. The lines appear to create a tube or tunnel, which would be round. We then adjust for the 3D effect, resulting in the lines appearing curved.
