By how much has your income gone up over the same period?

How does that affect the cost of motoring?

It means that although the purchase price of (say) a litre of petrol has
gone up it represents less as a percentage of your income (assuming no
changes other than inflation). Therefore the price of petrol has decreased.

If my disposable income had
doubled during the time concerned, I might have chosen to spend that
extra money on other things besides motoring. Therefore I am still
worse off than if fuel had remained at early-1990s prices.

Wrong, because petrol has increased at a slower rate than income therefore
people still have more to do with as they wish than at any point in the
history of motoring. Why? Because the cost of motoring has decreased over
the last 100 plus years.
