While Roger Castillo (Cyclists And Their Manners, August 21) may well be right, exactly the same faults - driving the wrong way up one-way streets, using mobiles and jumping red lights - can be levelled equally at car drivers, motorcyclists, bus and sulky drivers etc.

A car coming down the wrong way along a one-way street will hurt a lot more people than a bike in an accident. I'm not saying cyclists should be allowed to do it, but then neither should car drivers. For some strange reason bicycles have suddenly become public enemy number one for some drivers.

I should point out that locally one-way systems and other geographical barriers, including tunnels, were never considered or designed with cyclists in mind and barely include pedestrians, let alone walking a bike beside one. Cycling requires physical effort and one-way systems are there largely to thin out and control vehicular traffic.

Maybe it's time the ADT and local councils had a serious rethink about this; after all, buses are allowed to move against traffic on some roads, so why not bicycles under the right conditions?

Bicycle contra-flows? Mr Castillo may have unwittingly suggested a brilliant bicycle-friendly initiative. I'd certainly swap our appalling cycle lanes for one or two good contra-flows that took some of the toil out of pedalling and got more cars off the road; it would also make village cores more accessible and commercially viable rather than circulating around the periphery.

While not wishing to get into a spate about cars versus bikes, bikes also save Mr Castillo parking spaces and make for shorter traffic jams. Don't believe me, let's have a bike-free day. Everybody swaps their bike or motor bike for a car one day a year to really gridlock the whole island.

I can assure Mr Castillo that his letter has made me think seriously about my manners on the road. After all, I've got more to lose. But then will car drivers do the same?
