A few short months ago the prospect of diesel fuel breaking through the
£1.00 a litre barrier appeared to be unlikely, but with it now costing over
£1.20 a liter that's nudging £5.50 a gallon, this got me wondering just how
much it would have to reach before people on this newsgroup reached a point
where they would be seriously thinking about giving up their car? .. My own
threshold would be somewhere around £10.00 a gallon and that would be it.

Are you mad? You must be a lottery winner then. Current prices are at
breaking point. £10 per litre would mean £16250 per annum in my case just
for fuel to drive to work. I would need an extra income of £27,083 just to
support this single cost item. Then add Road Tax and insurance plus cost of
maintenance and car renewal.
