But we’re comparing getting a Kei truck instead of regular truck in this part of the conversation so it actually does make sense to discuss the safety question.
The conversation you want to have is elsewhere in this post.
No, I think OP is making a valid point. If you start with a Kei and just add in modern safety features and nothing else, the size of the vehicle will be a lot closer to the Kei than the other monstrosity.

I had already shared a link about modern Kei trucks in another comment, they get a safety rating of zero even with modern safety features.
I’m not saying the modern Kei must be safe. I’m saying if you do things to make it safer while prioritizing small size, you’ll end up with something a lot closer to the size of the Kei than the other car.
