The shuttle driver at the airport didn't seem to know about NextCar or where to take me. It's in the rental area of the Denver airport and everyone (all the shuttle riders, the shuttle driver) seemed very confused/surprised that's where I was going to get my rental car. Which does not imbue one with confidence when you're doing something for the first time. I don't know if this is how NextCar is at other airports, but at least at DEN it's not great. Also, when you show up, it's not a real person. It's a storage box with windows and some electronic kiosks inside, and terrible signage. The shuttle driver dropped us off in the right place but we thought it was just a storage thing - the signage was not good. So we walked all around until we figured out that's where we needed to be. When you get in there you press a button and someone logs on remotely and you talk to a remote virtual assistant through a screen. They're at least a real human and not some AI thing, but I did not like that. It was strange and weird and maybe convenient I guess but at the expense of being very unusual and weird. I did not like it at all.
