Set the penalty at a bit more than it would cost to divert round the
restriction.

How do you measure such a cost? Just extra miles (and hence gallons) of
driving polluting people living further out, or does my time have a value
too?

Like all such things, the answer will be a fudge based on wage levels and
fuel costs.

Call it twenty quid a trip as a starter, and if that doesn't put enough
off, then increase it. It's a penalty to discourage people, not a carrot
to entice people to update their transport.

My time as a semi-retired person, is probably worth less than someone
with an urgent appointment in Central London.

If I had an urgent appointment in Central London, I'd either use public
transport or a pushbike, as they are the fastest ways to get round the
City. By about 2030, all buses will be electric, as will most cabs.

the problem is that this, and similar bans in other cities, aren't being
proposed for 2030

they are being proposed for 2020
