Perhaps too broad: how do brands interact

I'm working on a sci fi setting, video gamey sort of exadurated light sci fi, but I'm stuck on my creativity, so I'll focus on A different area, how do different brands of, in this case particularly vehicles/electronics, brands/manufacturers interact in reguards to worldbuilding and culture, I'm going with that its the year 3000,and there are a gran turismo worth of different sci fi vehicles .

Also, what are some different types of categories of sci-fi vehicle, I've got: speeder, walker, VTOL, hovercraft, mech, jetbike... Not all publicly sold

Yeah, way too broad.

To simplify, I'd go with a 1950s American car manufacturer sensibility. Everyone competes with each other, and there's a troublingly high level of xenophobia in the advertising. (And honestly, if you're looking for how brands affect/are affected by the world, I'd focus on the advertising.)

There's only one or two models for every type of vehicle or device, they all focus on one or two aspects at the expense of others (with no exceptions), and no one thinks there's a market for a compact version of their product. Etc.
