I'm a California resident, I'm moving out of state to the east coast, for a new job, which is a 2-year contract, and I'll most likely end up in California again after the said two years.

Do I have to make sure to get rid of California licence plates and driver's licence, or risk being double-taxed on my state income taxes? (I don't own any real estate property, in California or elsewhere; and I plan to file as a part-year resident for the year in which I relocate to the east coast.)

Note that this question is not whether you can be in another state without getting a licence plate in said state, which might be illegal in said other state according to other state's law; but is about whether you can have a California licence plate in another state, without being a California resident and being subject to California income tax when not living in California and not physically working there, either.
