I am writing in reference to the story about miserable bus drivers ("The drivers are too miserable!", Post, April 27).

Not many drivers are, but a lot of the passengers are, especially on the Portishead to Bristol route.

First Bus has introduced buses with wrap-around advertising on this route. This advertising covers the whole bus, including the windows. It may be eye catching to those on the outside, but to those actually travelling in the bus, having paid a high fare to do so, it makes for a miserable journey. It means you cannot see out of the windows, there is only a blurred flickering impression.

Not one of the dozens of passengers I have spoken to is just indifferent to travelling on these buses. They dislike them intensely. What is more, travelling on them makes them feel ill, it gives them headaches, sickness, sore eyes, feelings of claustrophobia and disorientation, as they sometimes don't know where they are and have even missed their stop.

Many letters to First Bus have been ignored, but did produce just two brief comments. Their PR representative has told me that "the income this generates is important and helps ensure that we can invest in new vehicles and keep fares as low as possible". Surely revenue could still be raised from eye catching adverts that did not cover all the windows?

First's Assistant Business Manager understood my comments "that the view from the windows is extremely limited and unsettling" and that he would ask that adverts did not cover the windows. But commissioning this type of advertising must be a company decision, and First Bus continues to use these buses, despite the discomfort they cause their passengers.

There has been no other acknowledgement of this, even from Mr Justin Davies, the managing director of First Bristol Limited, whose message on First's website includes the words "safety and putting our customers first are our top priorities".

Of course First Bus must try to increase its revenue. Raising the number of passengers would seem to be a good way. But they have actually devised a successful deterrent to bus travel, on top of their high fares, because many passengers on this route say, if they have a choice, they would now avoid travelling at all on First Bus.

Passengers, and First Bus employees, say there is no point in contacting First Bus about this, because "they wouldn't listen". Sadly true, and this indifference would make anyone miserable.
