There is no state--Texas or any other--that considers a 17-year-old to be a legal adult. I've read on the internet (and based on your question it appears that you have too) that in Texas, the police will not force you to return home if you're 17, fully supporting yourself (ie NOT living with someone else), in a safe environment, still attending school, not on any kind of probation, etc. However, take that information with a grain of salt because I've seen a whole lot of information on the internet that I know for a fact isn't true. AND that's all irrelevant to your situation because (even if you go to Texas) you are not a resident of Texas. If the police locate you, they will pick you up and make arrangements to transport you back to Oregon. In addition, anyone who assist you, or knew that you were a runaway and failed to report your whereabouts, could be facing charges.

If your parents have legal custody of you, and presumably they do, you will need their permission.
It is called Auto Theft. The penalty for an adult is serious jail time. A 14 year old is a juvenile and as such will do no jail time. The penalty will be decided by a judge.

Yes, with parental permission
