It seems crazy to me that some people find roundabouts so hard. I’ve always found them pretty intuitive but I’m definitely biased, when I was learning to drive there were about 8 roundabouts of various sizes near my house and I’d invariably have to take at least 3 at the start of any journey.
It’s probably just because we’re so used to them here but pretty much everyone seems to know how they work. Off the top of my head the only exception is one badly designed roundabout where you’re meant to stay in the outer lane unless you’re taking one exit that’s practically a u-turn, people always take the inner lane (like you’d normally do) and have to change last second.
That seems iffy to me, that font only has upper case. I ran it through myself and got Caligula Regular, a free (afaik, check before use) font which seems to fit just as well.
