Can a V1 set off another V1??

V1s cause X-Band falses in close proximity to other RDs in my experience.

I run two v1s regularly in the same car. I try to keep them at least two feet apart and haven't seen any issues in either.

Now that being said, I could see one interfering with another if they were set front to back by the nature of their detection patterns, but I've never run across another v1 setting off either one of my v1s (or a single one when I just had one).
