Or... you need a person who is specialized in working on EVs. EVs are still not the majority, so anything different from the norm will need different training, and thusly higher hourly rates to work on them.
When Ford started making putting aluminum bodies on their F150s, they had special training programs for doing bodywork and repair on them. I guarantee that cost was passed down to you.
It may not even take longer to do the repairs, it might take the same amount of time once you learn how to work on them. That said, I guarantee the shops and insurance companies are recuperating the costs of that extra training.
When Ford makes a new car they write a large book on how to repair every body panel on it. For hidden parts how much damage was acceptable before you had to do something. All dealer body shops are required to have book before the dealer can on sell the fist car (along with books and training on other repairs). I believe most body shops don't buy this book, but at the time I worked for a company that made tools and those books were used to decide what special tools we needed to design/make next. I left before Tesla was a thing (2 years before the roadster), so I don't know what Tesla does, but I suspect this is one of those details they didn't realize was important.
