I can understand that they want to earn more. However, they have a responsibility to take care of their passengers. It may appear as if this new measure will stop them from going so fast, but I do have some misgivings.

Some drivers may accept the speed limiters and adhere to the rules, but some may not. Therefore the Transport Department must ensure there is adequate supervision of minibuses, with checks to ensure that they have fitted the speed limiter as required. Also, I think some monetary incentives should be offered to encourage drivers to have the speed limiters fitted.

Second, when deciding what the maximum setting should be on the device, we need to appreciate that expressways have different speed limits from ordinary roads. Therefore, there should be more consultations with minibus drivers and members of the public over this matter. I would suggest a limit of 70km/h.

Drivers who do not comply with the new speed-limiter rule should face fines. Without the co-operation of the minibus drivers, this plan cannot be successfully implemented. I hope they will co-operate with the government.

This plan should be implemented as soon as possible and extended to other forms of public transport. In this way, I hope we will begin to see a reduction in the rate of traffic accidents.

Should the city have a third free-to-air TV channel?

I would welcome such a channel. Television is a major form of entertainment for Hong Kong people. They enjoy watching news bulletins and lifestyle and travel programmes. You can also access different kinds of information through television.

At the moment, we only have two free-to-air providers and TVB is dominating the market.

As a number of academics have pointed out, we have little choice in this area of broadcasting. Viewers are forced to watch programmes that are of poor quality, and it is getting worse.

Soap operas lack originality, and vulgar game shows are shown repeatedly on our screens.

One of the reasons for this declining quality is that there is little or no competition. A third free-to-air channel would help to break the monopoly. With more competition, the three companies will be more eager to produce programmes of a higher quality. We will all benefit as we will have greater choice.

Most of us are fed up with the current situation, and hope that with a new competitor we can enjoy a more diverse broadcasting industry.

Because of the mid-term review of the licences of TVB and ATV, there has been a lot of discussion about the quality of service they provide. I believe that an additional free-to-air channel will help to improve the quality of television programmes.

Hongkongers are so used to just switching on and automatically watching TVB no matter what is on. I do not think this is good, because it means the broadcaster does not have to worry too much about the quality of its product.

For the most part, TVB broadcasts entertainment shows and soap operas. Seldom do you see a programme that has educational value and is meaningful.

A lot of the ideas in the programmes I see appear to have been copied from programmes in other countries. I think that if there was a third free-to-air channel, there would be more intense competition, and we would have greater choice and see an improvement in the quality of programmes.

I am sure the current broadcasters would gain as they would have to sharpen their competitive edge.

What do you think of this year's book fair?

I am not surprised that Ivy Ng (Talkback, July 24) has strongly opposed my views on the heated debate of the pseudo-models at the book fair (Talkback, July 21). But I would like to suggest to your correspondent that I do not apply twisted logic to justify the presence of the pseudo-models at the fair.

The fact is that the pseudo-models' publications were very popular, while other booksellers did not get many customers. The so-called bikini party was confined to only a few locations, but they drew a large number of customers.

There were plenty of opportunities for lovers of literature to enjoy the event.

We have to look at it logically. There is a demand for the pseudo-models. Their books are not classified as obscene or indecent, so why should they have been denied equal opportunity to promote them at the fair? Ms Ng claimed that their books had no true literary value. But who is entitled to pass judgment in that way? I do not think your correspondent has any right to discriminate.

These pseudo-models worked hard to promote themselves. Their events might have little cultural value, but the bottom line is that they had equal rights when it came to promoting their books.

There should be room at such a fair for different kinds of book lovers; it should not be exclusive. Ms Ng should respect the rights of others.
