They are not simply whinging. their livelihood is being destroyed.
Their complaint is not so much about the overall level of fuel costs, as the lack of a level playing field.
Whilst diesel prices vary so much within Europe truckers from other countries can come in using fuel bought at much lower cost.
We need co-ordination in fuel prices, but not as Sarkozny suggested to lower them, but to have a consistently high level.
This is due to poor political decisions, not just an inevitable rise in fuel prices, and the truckers are right to protest the incompetence.

EuroTunnel offers (last time I checked) a special service for British lorries.

Come down to Dover with just your cab (tractor) and we will transport it to France.

Drive less than 1 km on French soil, fill up with cheap French diesel, come back and we will rail you back to England.

It does not sound like France needs cheaper diesel !

Consistently high prices are what is needed, instead of inefficiently crossing the channel for no purpose other than those created by varying tax regimes.
The Channel tunnel should be transporting more goods by rail, not lorries to fill up their tanks.

The point is that (eg. in France) the pain is shunted right down to the little man, the fisher, the small independent truck co., the individual poor commuter, farmer, etc. Greek tanker owners pass the cost right down to their customers (though I have heard they are feeling pain as well) and they limp along. At the end of the chain, as the payees or customers are strapped, the goods and services (fish to the incredulous housewife, trucking charges to the on-the-ropes small manufacturer..) billed can no longer be sold / paid for. So they prefer to demonstrate, or give up and shut down.

Besides that, Sarkozy is a grinning bling-bling buffoon.
