Why are f1 cars required to run two different tires in dry?

In addition to what Alonzo said as quoted on this site on the Autosport site he is quoted as saying:

"I think it is the worst decision they made in a long time, because it is a ridiculous tyre for here, for Shanghai," he said.

"I don't know if Bridgestone made the decision or the FIA, but they have to reconsider this type of decision because we look ridiculous on television and we look ridiculous for the spectators, and it is a joke to be in front of TV six seconds slower.

"We will need to change the tyres after five or six laps, is our calculation, because this track is harder than Melbourne and there we only did eight or nine laps.

"And if they want to be funny and mix the results and have overtaking, they can do a better job – a funny solution, maybe they can put us on the wet tyres or something. Like this it looks more spectacular – the difference in the speed. I don't know...

"I'm very worried about this and I'm very sad about this, because we look strange in front of people."

Alonso also revealed that the drivers have not been consulted on which tyres should be used, and added that the Grand Prix Drivers' Association (GPDA) expressed their fears over safety on the issue following the Australian Grand Prix, when Robert Kubica and Sebastian Vettel collided while contesting second place.

"We expressed our concerns after Australia, after the accident of Robert Kubica and Sebastian Vettel – it was due to the difference of the speed," he said.

"He (Kubica) tried to overtake, Vettel was not in control of the car with that tyre, you cannot brake, you cannot turn-in, you cannot do anything. And then Robert had a big crash after that because he damaged the car.

"Then we expressed our concerns and now in the third race we have the same tyre at a worse circuit. This is something that we need to change immediately."

Alonso added that he considered both the super-soft and the hard tyres to be unsuited to Shanghai.

"I think the super-soft on this type of circuit with long, high-speed corners... in Turn 1 it will be destroyed and in Turn 10 there will be no more left tyre.

"One will be too hard and one will be too soft. The right tyre is at home! The soft tyre is at home, and this happened in Australia as well. And the understanding that this is for a better show, for overtaking...

"As I said, for a better show, maybe we can pick up our number and then whoever picks up number 15 can put on wet tyres, or whatever, and it is a better show and it's funny. Like this it is not funny."

This story supports my concerns about the safety of Brodgestones marketing exercise in F1.
Wouldn't it be much better for Bridgestone to use their immense technology to develope a dry conditons slick which could be used at all the circuits while delivering good performance and great reliability? This would be an accomplishment to crow about. An accomplishment to impress the whole world!
