It'd be interesting to see what the reaction is from people and companies in the field. Preemption legislation seems a little premature, to me. Sure, it would stop states from hindering autonomous-vehicle development, e.g. to protect entrenched interests or because of irrational fears, but it could also stop states interested in being on the forefront of research from doing more interesting things. It seems like the sort of thing you'd want when products were further along the development path and having a broad, harmonized-rules marketplace is necessary to move further, but not when most of the tech is still pretty early R&D work.
