If you are talking about taking a car solo, that's pretty expensive. It's hard to imagine a marginal cost under $0.23/mile for driving [1], so you are looking at a round-trip solo cost of $132 minimum - that's higher than flying (if you can plan it). Either way, I'm not sure how much autonomy changes things. You can get luxury buses overnight for $115 overnight (https://www.latimes.com/travel/deals/la-tr-money-20170903-story.html https://www.latimes.com/travel/deals/la-tr-money-20170903-st...) already which probably beats the comfort of a car anyway - how much will not paying a driver cut costs?
