Finding a cab on Orchard Road on a rainy day is the ultimate Singapore challenge. Either you queue for more than 30 minutes at one of the many taxi stands, or you succumb to using your mobile phone and pay the S$3 ($14) surcharge for someone to come and rescue you. Last week, deciding to avoid the rain, I called my regular company and was greeted not by the regularly grumpy woman asking me where I was, but by a computerised voice telling me my location and asking me to confirm it by just pressing a button. Three minutes later, my friendly taxi driver arrived. Now, I confess that I take taxis nearly every day (it is cheaper than owning a car and you do not have to worry about parking), but this was a first. My driver told me that the Global Positioning System satellite tracking had been on test for some time, but was now being put to use in the 5,000 Citicab fleet. He quickly added that since he has been using the technology, he has also been carrying his mobile phone to call back clients who have booked - just to make sure that the computer has the correct location. The problem with the new gadget, he said, was that it does not actually pinpoint clients' whereabouts, but gives a choice of six locations. What often happens is that the client presses the first choice (as I did), which is not always the right one (guilty!). 'It happens regularly,' he said. 'And then I get scolded for being late. So now, I call back everyone.' This, it seems, is called progress... Still, I think it is a pretty good invention - at least compared to some 'gadgets' which have been installed in Singapore's cabs, and which are definitely not welcome. Take for instance, the TV screens in the back of some vehicles. As a child, I used to dream that one day we would have TV in the car, but now I find it a real nuisance (along with music that I cannot stand and Chinese talk shows that I cannot understand). The problem of commercial TV in Singapore's transport is a real issue. Tourists might find it unusual and a great idea, but for locals, it can be a real pain. In the MRT, adverts are on a continuous, short loop, meaning that you can hear the same one up to eight times before getting off your train. In fact, advertising has become more and more inescapable in the city-state. Boarding a bus last week, I was greeted by a bunch of beauty products under a glass dome, displayed for all to see as they pay their fare. I guess the argument is that it is one way to keep down fares, but the general feeling is that it is really just driving profits ever higher. I just worry about what they will think of next.
