Sidecar is a c/2 orthogonal spaceship that was found by Hartmut Holzwart in 1992. Alternatively, it may refer just to the tagalong (displayed in green, in one phase it is made of a LWSS and a banana spark) that is attached to the heavyweight spaceship. One heavyweight spaceship can support two sidecars.
The sidecar can be destroyed by an eater 1 in a way that doesn't affect the heavyweight spaceship, which can be then destroyed by known means, e. g. with the block and pond.
More generally, a sidecar can refer to any spaceship component which is unstable on its own but can function when attached to the side of a spaceship, in much the same way that a tagalong can attach to the back of a spaceship or a pushalong to the front of a spaceship.[1]
Commonness
It first appeared naturally on May 12, 2019, in a G1 haul submitted to Catagolue by Rob Liston.[2]
Glider synthesis
The tagalong itself can be constructed via five gliders, so the entire spaceship can be constructed via eight gliders.
