just because there is a tax regime based on tailpipe emissions today doesn't mean the tax regime in 10 years time will be based on the same thing. As ICE car numbers are reduced it's inconceivable that tax will be based on the same philosophy, so to assume it will be and to state it will be a fact that old EVs wont be taxed is ridiculous, they might not be or they might not be, but you have no more proof one way or the other than anyone else and to do so really is illogical. If history tells us anything it is that Governments can an do whatever they want when they need more revenue.
Alright, let me rephrase: old EV's won't be targeted by pollution-based tax.
There's every possibility a new form of tax (not pollution) will be introduced, perhaps on public charging (I think most likely), perhaps yearly like current VED (but VED are never applied retrospectively), who knows. But one thing is for sure, those tax will not target older EV to get them off the road. Simply because it makes no logical, environmental sense, will be a political suicide.
Current toxic tax (on just 5 years old diesels) or fuel duty are favoured by groups promoting greener future (mostly quoted by the Independent article I posted earlier). Those kind of tax makes sense for the government: pleases one group
and rakes in the cash.
You then state production of a new EV is producing pollution during manufacture, so is it better to run a current ICE for some more years or scrap it and create pollution by buying a new EV, be nice to know which vehicle produces the most total pollution from the time when thinking about replacing one's car to the point of scrapping, albeit some of it conveniently in someone else's back yard in the EV's case.
Double standards?
There's no definite answer to this one. It will depend on your car's age and condition. But if you are looking to change (for example, your current car is beyond economical repair, or you just fancy a change), EV is well worth considering.
For example, if you are driving an old polluting diesel (Euro 4 or earlier) on mostly local stop/go traffic, a lot of time less than 20 miles. EV is perfect replacement and will help cut down toxic local pollution hugely. You can then keep the EV long term, like you did with the 12 year old Euro 4 diesel, and the longer you keep it the less pollution it generates per mile.
The manufacturing pollution of EV is offset within first few years of using it. The Bloomberg published, obviously biased research, shows if EV were powered by a grid that is 40% coal, 10 years later, EV will produce less pollution than ICE cars. That is completely ignoring any grid level improvement over next 10 years.

Congestion isn't so much the number of cars but lack of proper road planning and allowing cities and towns to become overcrowded.
The only evidence of parking education being needed is EV drivers parking their cars in designated charging places even though they aren't charging. They just figure a space has been saved specifically for them as they have an EV.
Congestion charge is different though. Its aim is to reduce congestion, reduce pollution is a nice by-product. At places with good public transport, congestion charge is a fantastic way to change the driving mentality.
Yes, parking EV in charging bays is no better than ICE car parked there, in fact, it's the same. I just wish chargers are more reliable and ticketing those people happens more often.
