Motoring is a massive cash cow for tax dependant UK. There is also an anti motoring background that has persisted since the red flag days, albeit with new ways to milk the cow being found. It will happen with EV motoring sometime soon. When a suitable balance point is reached for tax revenue of EV versus ICE there will be a change in grants, car charging tax introduced ( smart charging), battery recycling charge, increased taxes on ICE vehicles to push the change to EV. Like solar energy it is the early uptake that gains the better initial payback. As time goes on that benefit erodes. For London there are two charges, Congestion and ULEZ. Other cities are following suit.
In the meantime other major polluters are relatively untouched.
A big factor is undoubtedly the lobbying that takes place. Vested interests have big lobbying sectors to prevent or minimise negative legislation. Politicians are targeted both legitimately and illegally ( allegedly). The sleaze factor is currently making news.
