My guess is that they are buying time by having events with the R2 and R3/X over the next several months so that: 1) people can see them and it keeps interest for folks in different geographic areas; and 2) they can have active social media posts for the next 5 months on the vehicles. Then maybe...
I also went to the event today in NYC. First and foremost, the food and dessert table was excellent (lol…but really). Second, also learned that there will in fact be a rear wiper! It will likely be hidden and come from the top.
I'm attending the Wednesday one. I work 4, 10-hour shifts: M, T, Th, Fri. So, it works for me. Also plenty of other healthcare professionals (especially those in hospitals) may be working 12-hour shifts 3x/week. Plenty of job-workin' folks with a mid-day week that works. Also, free lunch! haha.
