carbon neutral petrol tanker

[Ivan]

Today I drove past a petrol tanker on the motorway. I think it was Shell, but I was too taken aback by the message on it's rear end 'THIS TANKER IS CARBON-NEUTRAL, ARE YOU?' I nearly crashed into the central reservation!

It may be used to take back petrol from customers who don't pay.

Certainly feels like it, Paul! If I see it again, I'll photograph it, to prove 1)that I am not made or 2)you are all just as mad as me
