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. The tagalong itself can be constructed via five gliders, so the entire spaceship can be constructed via eight gliders. One spaceship can support two sidecars.
The tagalong 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.
It first appeared naturally on May 12, 2019, in a G1 haul submitted to Catagolue by Rob Liston.[1]
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.[2]
