Sony’s taken its Japanese PetaMap system and added support for local petrol price data – which can then be viewed on your Sony GPS system, letting users shave fractions of a yen off the price of each litre – just like the UK-based web site PetrolPrices.com which does much the same thing. Only on a computer.
How extremely clever of them. Sadly, the cost benefits of using extra petrol to drive to a petrol station not on your usual route will be burned up in a few hundred metres of driving. You can’t beat The System. The System will be at your funeral, laughing, while wearing a red dress.
