It is like all the period drama where the towns and villages are always immaculately clean and everybody has nice clean, fresh from the dressmaker clothes, no poverty, dirt or rags. When we see coaches travelling along it is always in beautiful parkland scenery. We are never shown rutted muddy tracks, which is why gentlemen so often rode horses rather than travelling by coach and remember in the book (P&P) when Elizabeth Bennett walked from Longbourn to Netherfield Hall to see her sick sister, Jane she arrived with the bottom foot of her skirt and petticoat covered in mud - and she was probably trying to keep it above the dirt. Don't get that detail in television either.
