From my personal experience, for the car I got and my mom got, touchless meaning two things; I had an option to have it deliver right outside my house or pick it up from the Service Center that was 40 minutes away. I chose to have it delivered, they instructed us to check for issues and the paperworks are on a fedex folder to send out including the paperworks and registration. Key cards were left inside the car.
For my moms car, touchless delivery meant we had to go pick it up from a location, they gave us the keys, we checked the car by ourselves without any advisors around us, once we were ready to go, we have to talked to one of the advisors to sign something
