Point taken. What would you consider a reasonable notice period for car owners, when a change in legislation is due? (On the premise that you are not proposing that nothing should ever change).
I don't live in London, but I'd be happy with proposals that don't create an enormous surveillance State (and we know that when States have these sorts of intrusive powers, at some point they end up abusing them compared with their original 'purpose'), and I'd also be happy with something that was less expensive to implement.
E.g.
A tightening of car emissions regulations at point of sale.
An entry/exit fee to 'the zone' (not surveillance whilst in there).
An attempt to split car charging out from normal grid draw from your house charger. This can't be technical difficult, and most houses will not be charging EVs any time soon.
'Incentive' car taxes based on vehicle registered location, pushing polluting cars out of undesirable areas.
Charging based on mileage e.g. come MOT time.
I am happy to have these type of measures and sacrifice more immediate (authoritarian) changes, and allow the improvements to come more organically.
Yes, the above are not perfect and a determined person could fiddle them, but in the round they would go a long way to combating the environmental issues. No policy is a good use of Public (Gov) resources if you're plan at the outset is to make 100% sure 100% of the people comply 100% with the rules 100% of the time. Especially with something like this where 90%+ of a shift does wonders.
Some will say not hard or fast enough. Some will say stop interfering.
I think a more balanced approach, most importantly protecting people's freedom of movement without surveillance: it's this last point that gives me so much concern, and will only get worse and worse.
