Why can't companies figure out scale?

That does indeed look very off scale. How wide is the M35? The internet suggests 14 cm. Wikipedia says 236 cm for the real thing. There's obviously a lot of wiggle room depending on if it's wheel to wheel or fender to fender or mirror to mirror, but those measurements puts the scale between 1/16 and 1/17. 13cm would place it around 1/18, and 15 cm around 1/15.
The Subaru looks like it's the same width in that picture. That would place it closer to 1/13 - 1/12 ?

Interestingly, it looks like the Toyota Hilux body for the "1/16 WPL C14" would be a very close match to 1/14.
