Personally no. I'm just the type of person who don't travel much and I just think that it's not the best way of payment when you're going to rent a car for travel purposes. And when you have a car or someone in your family who has a car, I don't think you would even need to rent a car in other agencies. But as for others, maybe they would. It depends on their preferences. I just haven't tried it yet so I don't know how it works but of course someone would still want to try using Bitcoin for renting a car. Maybe if they have no other choice.
