Perhaps what is needed to reduce close passes outside shop doors

Or occasional cattle grids, arranged longitudinally in line with the

Possibly, though putting something down with no purpose other than to
trap and cause harm might be rather harsh.

The purpose would *not* be to trap or harm anyone. Everyone already
knows that cycling is not permitted on footways and in other
pedestrian-only areas.

Preventing cycling along footways by physical means is no different in
principle from placing obstacles to prevent motor-vehicles with three
or more wheels from being driven onto footways or into specified
pedestrian zones.

If you want prevention you stop or discourage people from going where
you don't want them to go. Prevention is not about harming them if they
go there.

No-one will harm them.

They might harm themselves, just as they will if they try to cycle
through a locked gate, or a brick wall.

Your suggestion is rather like fitting RPGs to speed cameras.

Not in the slightest.

Sensible people would not oppose that measure in either case.

Many people that don't ride bicycles aren't sensible about cycling.

You said it.
