By bad drivers what do you mean ?

Q: How is the fuel consumption test conducted.
A: The test is outlined in Directive 93/116/EC and provides results that are more representative of actual average on-road fuel consumption than previous tests. There are two parts: an urban and an extra-urban cycle. The cars tested have to be run-in and must have been driven for at least 1,800 miles (3,000 kilometres) before testing.
Urban Cycle:
The urban test cycle is carried out in a laboratory at an ambient temperature of 20oC to 30oC on a rolling road from a cold start, i.e. the engine has not run for several hours. The cycle consists of a series of accelerations, steady speeds, decelerations and idling. Maximum speed is 31mph (50km/h), average speed 12mph (19km/h) and the distance covered is 2.5 miles (4km).
Extra-Urban Cycle:
This cycle is conducted immediately following the urban cycle and consists of roughly half steady-speed driving and the remainder accelerations, decelerations, and some idling. Maximum speed is 75mph (120km/h), average speed is 39mph (63 km/h) and the distance covered is 4.3miles (7km).
Combined Fuel Consumption Figure:
The combined figure presented is for the urban and extra-urban cycle together. It is therefore an average of the two parts of the test, weighted by the distances covered in each part.
Thanks Hank and gaffer1986 for your replies.
On all previous cars the trip computer mpg has been very close the actual mpg. Also I've always managed to get close to the official combined mpg figure with my usual mix of short and long journeys. The combined figure for the Ibiza is 65.7mpg (over 50% higher than I'm getting).
On the Ibiza it's trip 2 that reads about 50mpg. I only reset trip 2 when I fill the tank then I calculate and record the mpg as always. With an actual mpg of 41 my trip is reading almost 25% high - if the trip computers are accurate there has to be something wrong somewhere.
Either, 1 - The engine is delivering 50mpg but an additional 25% of fuel is going elsewhere! or, 2 - The engine is delivering 41mpg but my trip computer is not recording all of the fuel being used.
The dealer checked it on Friday and there were no fault codes. And if "Computer says no" there can't be anything wrong. He didn't seem to have any idea what mpg these cars should deliver and was not concerned about getting only 41mpg with careful driving. They said they would send a DIS(?) report to SEAT. Does anyone know if I will hear from them again without me chasing it up myself?
Hank, I just clicked on your "Fuelly" link.
Diesel at £4.77 per gallon! I pay 122.9p per litre that's about £5.58 per gallon.
I don't know how much you paid but at 122.9p per litre £52.09 would get you 42.38 litres or 9.32 gallons. Over 411 miles that's 44.1MPG. That's better than the 37.6MPG quoted by fuelly. Unless your diesel really was £4.77 per gallon and if it was where can I get some.
They did not bother replying!!!!!!!!!!!!!!!!Hi S19 JGB,
What did SEAT reply when you told them you would reject the car as unfit for purpose?
** Official fuel consumption according to EU Directive 99/94. The consumption calculation according to 1999/100/EC is based on the unladen weight of the vehicle. Additional specifications can lead to a higher class and hence to consumption figures of this higher weight class. The driving style, road traffic conditions, environmental influences and vehicle condition can in practice lead to consumption figures which may differ from those calculated with this standard.
