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.
More generally but uncommonly, 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.
Synthesis and constructions
There is a 5-glider component that adds a sidecar to a HWSS, so the entire spaceship can be synthesised with 8 gliders. The easy synthesis has allowed for a period-60 sidecar gun and a stable glider-to-sidecar converter with repeat time 158 ticks.
