As far as I can understand from this, you should be able to use your own driver's license.
"...California does recognize a valid driver license that is issued by a foreign jurisdiction (country, state, territory) of which the license holder is a resident..."
You are still a resident of you own country; as long as your driver's license is valid you should not have a problem.

On this page, California DMV addresses who's a resident:
If you become a California resident, you must get a California DL within ten (10) days. Residency is established by voting in a California election, paying resident tuition, filing for a homeowner's property tax exemption, or any other privilege or benefit not ordinarily extended to nonresidents.
Thus, if you don't do the listed things, it looks like you can continue to use a valid drivers license from your home country. If that license is printed in a language other than English, you should obtain an International Drivers Permit (which is actually not a license, but only a translation into English of your license) to ease any interaction you might have with the authorities here.
