New zealand
Hi yes I love driving naked whenever I can too. Feels so free and liberating. I had a car with dark tints originally, then a van. Both were great for nude travel. I have a 4wd and the window tints aren't very dark. Tend to drive in the left lane so other drivers can't see your bottom half- still doesn't work with buses though. It is amazing how many people don't look around them though. What part of NZ are you in? I am in Tauranga.
I suspect most bus passengers have their nose in their phone these days. I generally try to pass with a reasonable speed differential so that even if anyone got a glimpse I'm past them before they react. A bigger challenge is to not end up alongside them at a queue at a red light. A school bus is one situation where word may pass around if you're not sufficiently discrete.
