Again what I don't like about bus fares in London (& elsewhere in this

change. Again a £1 fare valid for say two hours on any number of buses
would be a better solution.

Agreed.

Alternatively, it could be sold as a benefit of Oyster, as it is with
the Dutch Strippenkaart[1] - say, once you touch in for any bus
journey, you may touch in for free an unlimited number of further times
on different buses[2] within an hour, two hours or whatever. If that
offers a quick return, so be it - I don't think they'd lose a lot from
people doing that.

It would also be completely immune to fraud, unlike a single ticket
which could be passed on. As it's a disadvantage to have to tack a bus
journey onto the end of a Tube or rail journey, you could also either
heavily discount the bus fare if you touch in and out for a Tube or
rail journey 1/2 hours before or after the bus journey, or make it
completely free in such a situation.

[1] Actually, as singles are just 2- or 3-strip Strippenkaarten at an
inflated price, it applies to those as well, but the principle is
there.

[2] to prevent 'pass-back' fraud, i.e. the same Oyster being passed out
of the window to another pax and used again on the same bus.
