Today i saw an older lady (roughly 50) with what appeared to be a V1 in her window while I was on the freeway. It looked like she was using the hardwire phone line instead of the coiled power cable (it was not hardwired) and she actually had it mounted pretty high up.
Its amazing since I never see anybody with a V1 and probably about the 5th v1 I have ever seen in another vehicle.
One other time I actually urged someone to pull down their window after I saw their visor mounted V1 and I chatted quickly asking them about how they liked their V1. They told me they loved it.
