I mean, I don't think my perception is warped by what I see. But by "am I willing to risk that my repair will kill someone, because they wanted cheaper repair"? Or even if not kill, maybe just burn down their car (+ house,...). "Am I willing to use cheap tools, not rated for 800V (or 400V) god knows how many Amps?". Because this is not software development - you can be killed REALLY quickly working on a HV EV battery pack. It's no joke. For sure it'll cost more than working on a regular car, where there is danger, but a lot less. And that's just the basic thinking, without going deeper into why its more expensive to repair stuff like this.
