Emotional support

So, I (40/M) struggle with my health, both physically and mentally. This isn't really the place for that, but here goes my rant.

I have a 2021 Kia Sorento that I use to drive for Lyft. It is a 5-passenger full size SUV. I am a full-timer, so I pretty much just work, and sleep. I am able to make a decent living, but my question is, AITA, If I delete, and re-register my vehicle to include four seat belts, reserving the front seat for One of my kids as sort of a ride-along situation on the weekends? People bring untrained "service animals" in my car all the time. I don't mind dogs, I just don't like lying. So do you think I have a case for a "service kid"? I'm kind of serious, but also not. Lol.
