Sounds like someone with more than the maturity of a fruit fly! I've been up to a guestimated 65-75 in mine without a top. I stick up about like the Gumball Rally one posted a few posts back, Black with flames. I'm looking thru the middle of the upper pane. The buffeting was pretty heavy. The wind seeks the low pressure behind the windshield, meaning it hits the back of your head. With the top, I'd guess it's getting whipped. Here's a similar one, full height windshield with a top driven around a parking lot. Didn't find a highway video of one. www.youtube.com/watch?v=oMQpthtPvuE The guy that built one for power tour had a half windshield and no top. He's posted a number of videos.
The reason I ask if I ever buy or build one I will drive it cross country and likely would run into some weather - rain- and a top would be handy maybe. I might have a little maturity but likely less common sense. Not sure if a top could be stowed easily either. Dan
Dan, take a look at @Tim_with_a_T 's build. He's going to the effort to make it as weatherproof as possible for the PNW weather. Any roadster is going to be less sealed than even a convertible. https://www.jalopyjournal.com/forum/threads/the-belly-button-bucket-build-thread.1000590/
