M: Do you know the thing that’s always struck me as odd about opinion polls?
W: What’s that?
M: The percentages. Lake recently there was a survey about what people thought about traffic, and petrol prices, and public car parks. In some car parks it now costs something like 5 pounds to park a car for half an hour.
W: Yeah, but I don’t see what you’re getting at.
M: What I mean is the percentages in the results. So there might be 70％ of people who complained about high petrol prices, and 60％ who want to see the traffic reduced, and 65％ who think car park charges are too high. Does that mean that there are 35％ who actually think the charges are OK and would even be prepared to pay more, and another 30％ who think petrol prices are OK? I mean that’s absurd. I don’t know anyone who doesn’t think they’re too high.
W: Well, actually I think we should pay more.
M: Come on, you’re joking.
W: No, seriously. I think we should pay more for petrol, even twice as much maybe, and certainly far more for inner city car parks.
M: But why?
W: More taxes should be charged on petrol, I think, to discourage people from using cars, and a kind of graded charging system for car parks depending on how far they are from the city center.
M: What do you mean?
W: Well, if you park your car quite far from the city center then you pay a nominal amount as a kind of reward for not polluting the city center. Well, the closer you get to the center, the more you are penalized. Prices in the center should be totally prohibitive. I mean with an efficient bus or train service there’s no excuse for using cars.
M: Yeah, but you can’t penalize people who don’t use their car to go into town. I mean if you doubled the price of petrol, it would cost people a fortune to go anywhere, even on short trips, and especially on holidays.
W: Don’t use your car then. Use a train.
M: But what about lorries? I mean they use a lot of petrol to transport goods from one place to another.
W: So what’s to stop these goods from being transported by train or even via canal?
M: Well, anyway, I still can’t believe that 30％ of those people who said car park charges were OK all think the same as you,
W: Well, maybe that’s where you are wrong. Just think about what I’ve said and you’ll realize that perhaps it’s not so stupid as it sounds.
