I'm not saying I know this person is an asshole because they drive a large, obnoxious vehicle every day. I'm saying I see people who drive large, obnoxious vehicles on a daily basis and as such it wouldn't surprise me if this person also drove this large, obnoxious vehicle on a daily basis because I've seen others do it. It's not outside the realm of possibility that this person does use this as more than a "toy" just as much as it's possible that this is the only time it was ever on-road.

If this person drives this vehicle regularly in relatively urban areas (or really much anywhere except mostly on empty roads or off road) then I'd be disappointed and frustrated that their toy is something that has been modified in a way that makes it larger and more dangerous to both other drivers and pedestrians. That's not to say I think they're doing that specifically to be more dangerous to everyone else, but the net effect is still the same. Their modifications have made it harder to see others close to the car, made it easier for others to go under the vehicle in the event of an accident, and made it more likely to tumble in a crash.

That all being said, my experience with the type of people who install modifications like this to their vehicles would suggest they're an asshole who's either apathetic to the danger they cause others or like these modifications specifically because it pisses people off. Just as you said I don't know from this single photo whether this person fits that mold and I'm not going to pretend I do, but I'm also not going to give them the benefit of the doubt.

You may feel comfortable introducing the possibility and almost insisting that their vehicle is a toy, but personally I'm against calling almost any car or truck a "toy", much less one that has wheels that look taller than many people.
