(Kor, I'm playing Littlefoot, so could you edit that post and have someone else say it, like Diver.)
"Well, to give you a good comparison of how fast we are going, Fast-Runners are known to run at a speed of up to 50 kilometers per hour," said Elizabeth.
"In city streets like these, vehicles typically travel at about that same speed, but on roads like the highway, they typically go twice as fast," continued Steven. "And that's only how fast they're allowed to go. The top speed of most vehicles is about four times as fast as a Fast-Runner, and some vehicles can go even faster than that. But there's a rule called 'speed limit' that, depending on which type of road you're on, you're not allowed to go any faster than a certain speed. It helps reduce the chances of a collision, and, like I said earlier, collisions between vehicles are often deadly."
"That's good," said Littlefoot. "Anything that can save lives is a good thing."
(For those of you who don't use metric, 50 kilometers per hour is about 30 miles per hour.)
