Sorry to pee on bonfires but I don't believe that charge free access will be given to 120g/km cars or less when October comes - this rule was going to be enacted in Feb this year but got put back as there were questions being asked by greenies.....
Ken got flack for letting LPG motors and hybrid Lexii (Lexus plural?) with 4 litre engines in that produce 250g/km. The rule on 120> is likely to open the floodgates and result in wait for it... congestion! Every manufactirer has now tweaked their 1.6 diesel ECUs to produce a cheap 119g/km car so there will be loads of them about in time (I know the level of cars producing below the threshold is only 5% but with the price of fuel at £1 plus ltr and raod tax on the up - won't be long before they are common)
My money is on the level being reduced to 100g/km or less so that VW Bluemotion drivers will be the only lot allowed in, gawd forbid! There ends my Sunday transport sermon.
