If you wanted to make a car with the same outside dimensions today you could barely cram two people in it, due to all the mandatory crumple zones etc.
Of course consumer demand is also part of it, but in some cases car manufacturers are still making 1980s design cars today (e.g. the 79 series Toyota land cruiser), they're just outlawed in Europe due to safety, pollution etc. regulations.

I'm talking about official safety ratings, e.g. this in the Euro NCAP:
Although as that page explains the particular bias I had in mind was "fixed" in 2020, now it's a 1400 kg mobile trolley, so heavier cars are tested somewhat more realistically.

Well, no. You said that cars are larger because of safety regulations.
But the obvious rebuttal to this is that larger cars have been trending upward for decades, and the most obvious proof of this is the decline of the sedan in favor of the SUV.

These were larger cars than the average as well. The 90s Mercedes E-Class doors were significantly larger and heavier than the ones in a Toyota Camry.
A current generation Mercedes E-Class is also larger than the one from 30 years ago, mostly because it has gone through a significant increase in interior space. Again, this is not something only Mercedes has done to their line, all automakers have gone down the same route.

That car is roughly the same size of a Volkswagen Polo, which fits 4 people, and holds pretty much the same volume in the trunk. The Polo has an five star EURONCAP rating. Hell, even the SMART Fortwo is a pretty safe car, and it's mostly plastic.
Yes, small cars exist and are safe too, but people just like larger cars better.
Yes, but we're not talking about what's more common, but about how recent regulatory changes affected car design.

> car dimensions are generally larger because we ourselves have become larger and taller.
This is mostly due to changed regulations. Look at e.g. a 1980 model of a Toyota Corolla:
