If I were looking for subtle trouble, I'd look at the brain, which might be influenced in its development by a psychoactive chemical in childhood.
And at the wetware that runs on it.
Not at the chassis.

@Treczoks London residents or workers may not regret that. If you do, in your newer car, or by train, you may find the air is a bit nicer.

@HikuNoir @Emperor
Gargle with some if you like.

You may care to consider that nerve agents, as with other war gases, are optimised to be lethal or disabling on exposure after deployment, and then decay, allowing occupation of territory etc.

You may also care to consider the targetting of the agent in these particular instances, and the availability of high-quality intensive care facilities.

@Patch @Hogger85 It is going to be a standard need at holiday and break places.

@Hossenfeffer It'll affect around 10 000 000 people, I think.
The effect is better air to breath and less illness caused.
If you were to tell them you were going to improve their air, but you'd decided to give them 5 years notice rather than one year, I think stepping back quickly out of reach would bd wise.

The effects are of course incremental.

Is this a new thing?

The MOT was introduced last century, I forget when it changed from "not a smokescreen" to limited exhsust emissions. But, no.

@Hossenfeffer @Emperor is 5 years practical with a 5 year election cycle?

Are you calling for no detail of any plan to be adjustable in less than 5 years?

When we're the ULEZ plans, in some form, published, please?

@Oneeightnine @mackwinston
Shares enough sponsors and characteristics for the deprecatory simile to be very apt, I think. NSIT and so on. Why do you differ?

@tinned_tomatoes @Emperor
He can't afford the lawyers.

@Syldon Did it clear up your belief there must be a central control point?

(If I get to that WP article I might change "are federated" to "may federate" because it is more precise, and because that is part of the methods which substitute for central oversight.

@someguy3 @Oneeightnine
There may be local variations?

@Ace_of_spades @rmuk

Your resolution to do no business with any company who have ever employed a criminal, even if modified to specify a restricted class if crimes, is interesting, but I think you will starve, unamused, and self-unemployed.

If of course any crime is shown to have been committed, and you may have implies, if employment then continues.

The Sun does not have a reputation for accuracy.

And the story seemed tenuous, and to assert a remarkable market rate.
