No waiting, I believe the delivery times are set so to mitigate any wait times. It was pretty straightforward, paperwork was no more than 5 minutes. The walkthrough of the vehicle was another 10 minutes which consisted of showing you the basics of using the vehicle, creating your driver profile, and connecting your key card to your app. About 15 minutes in total.
The rest is up to you, I spent about 20 minutes familiarizing myself with the infotainment system in the parking lot and another 10 minutes driving around the lot getting used to it which they recommend.
