Upon summons through whatever electronic device of the future we'll be using, the EZ-Ultimo could theoretically be yours for any amount of time up to a day. The goal isn't to cram a bunch of people in through ride-sharing, but rather to offer a "premium" experience on the way to your destination. It looks like a nicely appointed living room on the inside with a couch, swivel chair and luxurious French design. The swiveling chair even slides out to meet the rider. If that reminds you of GM concepts from the 1950s, you're not wrong. Some things just don't change. Renault says it even used marble on the interior — clearly, weight savings was not the goal here.
