Complexity in what sense? Level of hardware integration? # of embedded controllers? Amount of time necessary to familiarize oneself with the operation of the system?

[edit for readability] Complexity in every sense, at every stage of the design, testing, fabrication, and delivery. From discerning appropriate tactics for the coming century (which are used to produce design requirements that equipment is designed against) to writing the user's and maintainer's manuals, to the number of people required to get a particular sub-system into production, and so on. The bottom line is that a modern tank requires more people, more knowledge, more complex (number of parts, functionality, materials selection, fabrication, testing, etc.) and interconnected sub-systems, more complex manufacturing techniques, tighter tolerances (sometimes) (which lead to more complex methods of measure), more exacting specifications, etc., than a modern consumer vehicle. A standard automobile may have 20 to 50 microcontrollers that talk to each other on one CAN bus. A modern tank has at least 3 independent communication networks, an electrically isolated diagnostics system, distinct optics systems for the commander and pilot and gunner, a fire control sub-system, and so on. Each of these subsystems is immensely complex, designed and manufactured to exacting specifications for durability and maintainability. The specifications for each are so exact, that any subsystem can be torn out and another designed to the same spec can be swapped in. This is no trivial feat. This isn't like a new set of rims onto your car. It isn't even akin to piggy-backing or changing out the ECU in your car. It is at a whole different level, because each sub-system has to integrate with at least two other sub-systems (power and communications). This is like being able to tear out the autopilot portion of your Tesla and swap in some other company's autopilot, while keeping the rest of the systems intact.

Is your car radiation hardened to withstand an indirect nuclear attack? (tanks are) what about biological filters for the air? (telsa made waves a few years ago with its filtering, which is a lower standard). What requirements does your Chevy have to survive IED's, gunfire, and mines? What about real all wheel drive, and the ability to ford small ditches, etc (most of the wheeled military vehicles have very high ground clearance)
