How come there's not more interest in LPG?

Also, there is a myth that gas prices are about to rocket. The duty has been fixed for the next 3 budgets.

Do not underestimate the governments ability to turn tails on itself. 10p Tax, 2p Fuel Duty and Green Road Tax, for a start.

Dont kid yourself that if LPG got popular that it wouldnt get massive tax increases.
