HMRC mileage allowance - is it ever going to change?

[CIS121]

Is this ever going to change? I'm sure the upper rate was 45p per mile a few years ago and with the almost doubling of fuel prices since 2002, the 40p a mile isn't representative of the cost of running a car anymore. With all tehgreenies around, I'm not sure whether Hector is going to do anything about this.
