Why does self driving impact this at all? You can already lend out your car for other people to drive, and there are numerous companies that do exactly that as their entire business model. So this is a serious question, in what way does self driving cars mean your personal car is going to be used more? The only people for whom self-driving cars represent an actual real world monetary win are people and companies that transport people and things. So public transport, trucking companies, uber, etc - for them self driving would mean no longer having to pay for drivers. For every other group self driving has no financial impact on the value of the car (except possibly tremendously devaluing any existing cars where a component of their value is current generation "self driving").
