First off, I love how the car is intuitively matched to the subject. It's hilarious because an inanimate object is worth a thousand words.
Jerry has phenomenal access to these guys and can relate as a professional peer. How often do you get to listen in on that type of conversation? These guys are giants and might have been around the block a few times. I think that's incredible. I especially enjoyed Bob Einstein's episode and Larry David's incognito moves in the diner.
Something that came to mind for me was how nice it is to see someone stay true to who they are and what they think is funny. It's also good to see comedians sussing out what exactly is funny about something, finding the funny or following the game as kids say nowadays.
I wouldn't mind seeing expanded versions, or repeat visits to some of these people.
Overall it's some of the best webseries content I've ever seen. I enjoy real talk (Dinner For Five with Jon Favreau would be another show) and can't wait to see more episodes of this online.
