Rental car companies already use airline-like pricing schemes, with a mandatory minimum rental period of 24 hours. One of Zipcar's selling points is that their pricing scheme is simpler and more granular. If Zipcar changed their pricing scheme, they'd become just another rental car company in the minds of their customers.
I suspect that there will always be people who prefer the more straightforward style of pricing. After all, knowing exactly how much you're going to pay and knowing you won't be paying for any unnecessary hours counts as a feature for a lot of people. It's like buying a Linode. It might not be the cheapest option for all use cases, but it gives you peace of mind.
