It is pretty common in audio, many microphones and other di boxes etc require +48v. You supply the 48v and they give you the AC audio signal down the same line.

You can have a shielded cable. The shielding is grounded.
but you want the power and data on same wire the power wire will have noise how you going to clean that up build some massive filter at the distribution of power supplies. Seems like a whacked idea for a ice vehicle imo alright on a small device that doesn't use much power or have alot of switching going on and can have a filtered power supply.

Seems to me like alot of extra electronics would be needed like extra filtering, impedence correction as well wave shifting for next to no gain over current systems for data in cars. The central point for data in a car is called a gateway FYI. Been around for years as well as communications via data digital dc is whats used, modern looms are way smaller than their 90s counterparts
When you are using cruise control and the car decides it needs to go faster / put its foot down, it is a computer module talking to a servo or similar that pulls the accelerator cable !
