Motorway Light Speed

I took this photo while we were on the way home from university, driving down a motorway (i cant remember which one).

The wiggles in the lines are caused by camera shaked, but i like them like that.
In the phot there are four lines, two on each side. These come from the sets of 'double lamp posts' on either side of the road.

This was taken with a shutter speed of 2 seconds
