That word is not niche, and is not cycling related. It really is a very common word. Almost everybody who drives a car will have come across it, unless they never drive outside a city.
I had a car from 2019 till 2014. I never used the word verge. I never had to. I never came across it. At least from what I remember. MAYBE back then I knew it. Maybe. But not now. The guy replying to me, didn't explain what the word meant. Please review what I wrote about that.
