I'm not sure about it: in most episodes, RIck's car shows and uses no weapons. When it does, it shows quite large energy cannons. AFAIK, it's not possible to make folding vehicle weapons in Factorio, and constant having constant of big guns won't look canonical. Also, this would probably require either development of some energy ammunition, or usage of vanilla projectiles, which is also not canonical.
So, for now, I just decided to make a large equipment grid to allow usage of laser turrets :)
Yeah, they got nerfed in F2 SA, but there are other mods to fix this... However, if someone will suggest a good idea for car spaceship weapons, I'll consider implementing it.
