] At least we modern travelers have the advantage of continuing our journey in comfortable automobiles on paved roads. From what I've read, a Regency coach-ride was a bone-jarring experience, whether you rode inside the coach (packed in closely with people smelling of body odor and/or liquor) or outside where you were exposed to the elements and probably in occasional fear of falling off.

In one of her letters Jane Austen is writing about the trip she and her father and mother did from Godmersham to Steventon in Oktober 1789.
They had gone there because her brother Edward had just taken possession of the house after Mrs Knight moved elswhere. (Cassandra stayed on at Godmersham).
It was a journey of about 120 miles. They made two stops on the way.
One in Dartford and one in Staines. So they made on average 40 miles/day, travelling perhaps six hours a day. And speed very much dependant on the horses and the condition of the road.

She says about the stretch from Rochester to Dartford: "Our next stage was not quite as expeditiously performed; the road was heavy and our horses very indifferent." And further: "After we had been here a quarter of an hour it was discovered that my writing and dressing boxes had been by accident put into a chaise which was just packing off as we came in,and were driven away towards Gravesend in their way to the West Indies." Well, they sent a man on horse to fetch it back.

And she writes: "My day's journey has been pleasanter in every respect than I expected. I have been very little crowded and by no means unhappy." It looks like they had fellow travellers. But I suppose it was possible to hire a private coach if you could afford it.

And then: "We met with no adventures at all in our Journey yesterday,except that our Trunk had nearly slipt off,& we were obliged to stop at Hartley to have our wheels greazed."
No highway men in sight!
