Racetrack[1] is an induction coil.

It can be welded onto itself to form racetrack-weld-racetrack (shown below), four of which form cloverleaf interchange.

Together with an unnamed still life (apgcode xs24_259aczcid1d93), the cis-mirrored racetrack is the largest still life (with 24 cells) known to be constructible in 4 gliders.
