There are a few idiots of course (as in all walks of life), but most are sensible.The problem is a racing cyclist doing 25 MPH is a danger on the combined cycle/pedestrian way, but a child doing 3 MPH would be a danger mixed with motorised transport, so simple way is a speed limit on combined cycle/pedestrian ways.
I used to live in a town where the promenade was mixed access. There were a couple of near misses, so the local cycling clubs took it upon themselves to 'self police' the area.
Much better that than to simply try and legislate any problems away.
(Would love to hear how you would enforce a speed limit on cyclists btw!)
The same could be said about cycling in some areas, given the appalling state of the roads and the bad standards of some car/lorry drivers vis-a-vis cyclists!Common sense says use the path, law says use the road, why can't we have some common sense?
