I cam across a this post on the E-Reads blog. I think it's worth your time to go over and read the rest of it.
As a hansom cab driver of long standing I am writing to voice my objection to opening our public roadways to motor vehicle carriages for hire. Not only will this action devastate a grand tradition, it will take food from the mouths of children, notably my own. The inferior training and professionalism of these opportunistic motor carriage drivers represents a danger to the largely uninformed public, and their presence flies in the face of the people’s stated preference — indeed, their fond affection — for the hansom cab. The horses themselves are entitled to work for their living, as they have for generations stretching back to the Garden.
Yours most humbly,
