FYI, it looks like the Chicago event has been changed to 2 days only now...April 24-25. Website also states the Block Party will be coming to the Skokie, IL location as well, but no further details.
No one is forcing anyone into viewing the R2 in a crowded space, and certainly not forcing anyone to take delivery of a vehicle prior to test drives. If test driving the vehicle ahead of purchase is important (understandably), then be patient and wait.
