The hapless National Highways Wriggling Department has come up with this beauty about the impact of their scheme at Stonehenge:

“Predicted overall CO2e emissions have decreased” due to an updated matrix which has an “updated fleet mix including the projected uptake of electric vehicles up to 2050”.

Trouble is one of the main reasons English Heritage et al support the scheme is that there is noise and fumes from the road which reduces the experience for visitors to the stones. There’s very little actually, but even if there was then for every additional electric car National Highways postulates there’s an equal weakening of reasons for English Heritage’s support!
