E.g. if your tank is empty, you're willing to pay an exorbitant price, but you certainly won't be happy about it.
So, I think it depends a little on the actual implementation. If this really is about giving people who are very price sensitive a discount I don't think people will mind a lot, but if these algorithms learn to gouge people who are in a predicament, they won't be happy.
Me? When I hit a quarter tank I go fill up. It's a fuel hungry sports sedan that runs on premium, I resigned myself to the fuel expenses before I even purchased the car. I honestly don't even look at the prices because it's just really not worth the time to worry about for me.
In the case of musicians, most of them undersupply and underprice their tickets, which means that there's a market for reselling. For a variety of reasons, they keep prices low so as to ensure a sold out venue as best they're capable, and when prices are lower than they ought to be, ensures a market for resellers. Resellers help offload the risk to the original sellers, but if the sellers were capable of maximizing profits in the first place, buyers would benefit by not having to deal with the perils associated with gray market sales. Also, the artists / venue / middlemen would make more money.
