Who has the fastest speed limit in the world?

Okay, here's a shot at editing that with a more personal and natural feel:

"So, who's got the fastest speed limit in the world? Honestly, when I looked it up, I was a little…underwhelmed! Turns out, it's only 160 km/h (that's about 99 mph). I don’t know about you, but I was expecting something WAY crazier, right? Like, I remember reading somewhere about how back in 1861, the speed limit was a measly 10 mph! Can you even imagine? That feels like crawling now! Talk about a different world. But even 99 mph... I feel like with how powerful cars are these days, shouldn't we be able to, you know, safely go a little faster? I'd be curious to see what would happen if a country actually pushed those limits... within reason, of course! Maybe with special driver training or something? Just a thought!"
