Thanks for "the giftie"*

Interesting that the high UK petrol taxation has effectively acted as a buffer against price increases: equivalent of $6.50 per (US) gallon 13 months ago vs $6.95 today.
Also, Dumfries and Galloway, being "the middle of nowhere" as far as the UK is concerned (far from the Scottish Central Belt; not the end point of any motorway; far from the oil refineries; rural train service levels) will tend to have significantly higher petrol prices than elsewhere.

In Scotland, unlike (particularly southern) England, the "usual" commute time tends to be closer to one hour rather than two, so people will consider York - London commutes (because it is inside the magic 2 hr mark), but not York - Edinburgh. This may tend to bring the average down.

what exactly is the price per litre?
I wrote about prices in the UK around a month ago when we reached a new record average price of 96.13p:

The point about travel times is interesting and I can certainly believe it is a universal.  I wonder however what a similar analysis on travel costs would show though.  What proportion of income has typically been spent on travel over the ages?  I suspect that has been falling, certainly over the last couple of decades in the UK the cost of motoring has been falling.
