This is a good point but they seem like slightly separate concerns in a sense. My limited understanding is that truck drivers tend to rest where they hit their legal limit which will often be a lay-by rather than a proper truck stop. Perhaps we could include charging points in most lay-bys to get an overlap in charging vs. rest breaks but it seems to me a shorter charging process via swapping in a truck stop would still be advantageous since the rest break and charging stop won't necessarily overlap in most cases.
