well, a more imaginative, sports-care-like name would be a "crazy eight". I don't know whether there was much marketing in ancient Rome.
"Did you see Lucius's new sport litter?"
"Sport litter - you mean like the box from a new set of jogging sandals?"
"No, like the Litter you ride around in."
"We really need a better word for it."
"Maybe if you would just let us speak Latin like normal people, instead of this groovy trendy English nonsense..."
"Oh sure, and then what? I'm supposed to go work in Brittania next month after the Calends."
"Then what? We wouldn't mix up a perfectly good mode of transport with trash."
"Okay fine. But did you see it? It's a sport job - all the fancy paintwork and powered by 8 independent powerslaves."
"Powerslaves?"
"You know, big athletic buff guys who can run fast."
"Faster than a horse?"
"No, why?"
"Because if you really want to impress the girls and get Flavia Silvanus onto your cubile...sorry, bed, you might consider a chariot. Sleek, fast..."
"No roof or curtains."
"Oh, right. So, you think..."
"He had Flavia in the litter last week."
"And she..."
"Nobody really knows. She got in, and he ordered the slaves to get going at a pretty fast run. I mean, for a Litter, it was really moving through the streets. But he might have been paying more attention to Flavia than to his driving, because he really just let the slaves go, and as I said they were running, with no real direction."
"Problem with self driving vehicles, eh? So what happened?"
"Well ultimately they ran straight out a gate and then one of the slaves tripped and the whole thing flipped over into the Tiber. That's 8 slaves crucified right there."
"Why? Couldn't they have just picked the thing out of the river?"
"No, Lucius got something called "insurance". It's kind of like gambling. They decided to give him 500 Denarii instead of fixing it - they called it a write off, but it also meant that the slaves all get written off, or crucified really, as well."
"That's a bit harsh. Why not just re-sell the slaves?"
"I think they would have done, but you know, Flavia was all wet from the river, and her dad, you know Caesar's cousin, was pretty upset."
"So what's Lucius doing with the big 5 C Denari?"
"Buying a chariot, I think. Considering the temper of Flavia's dad, he's got to go fast and far."
"He should try Brittannia."
