Don't jump on me and this is my personal experience: I have no problems with motorcyclists and I don't think it would be a bad thing if we shared it officially - after all, they currently stray onto the bus lanes, as the car lanes are normally clogged up.

Although I agree that Jenny Jones (and Ken Livingstone) have done a marvellous job of promoting cycling in the capital I rather feel we separate ourselves by terming us as a 'cycling movement' surely the bigger picture is that we are about 'integrated transport' in London. There are now apparently, over 500,000 cycle trips made every day into the capital, cycling should be part of the major transport strategy in London.

I am praying that he gets rid of bendy buses - they are far more dangerous than motorcyclists.

The fundamental question is should motorcycle commuting be promoted. A motorcycle with one rider is no more fuel- or space-efficient than a car containing 4. It's noisier, and statistically more likely to hit a pedestrian or cyclist per mile ridden. You may argue that most cars in London are single-occupied, but the congestion charge applies just the same to full cars and empty.

If you do promote motorcycling, you'll get more motorcycles everywhere, not just in bus lanes. I think that would be bad for London, whereas increased cycling gives clear benefits to everyone.

Allowing bicycles in buslanes was not, originally, a pro-cycling move. It was to stop them getting in the way of motor traffic in the non-bus lane. Motorcycles can keep up so don't need this exemption.

Colin: when did you EVER see a car containing 4 people in London? I thought someone had enacted a law saying single occupancy only! And I'd like to see your source on the accidents per mile ridden. If promoting Powered Two Wheel use gets even a few cars off the road then both cyclists and m-bikers win.

Aside from the obvious dangers and inconveniences of allowing motorbikes in bus lanes, it's also pretty unpleasant having to sit behind a line of motorbikes waiting illegally at the advanced stop line with their exhausts pointing up in your face.

Stuart Fordyce: "Motorcyclists pay road tax like other road users..."

Actually, they don't - and nor does anyone else, since Road Tax was abolished about 70 years ago. Roads are paid for out of general taxation, so we all contribute to them, whether we drive a 10-ton truck or ride a bicycle.

But the substantive point is that having motorcycles in bus lanes is horrible for cyclists. Of course most of them are well-behaved, but the minority are aggressive and dangerous. I've lost count of the number of times I've been buzzed by riders coming far too close (even sometimes overtaken on the inside), and it's really a frightening experience. I wish Johnson would change his mind about this; if he wants to do something useful, he could campaign against motorcyclists' habit of occupying the advanced stop line area and - even better - stop the increasing abuse of cycle lanes by motorcyclists. Now that really would be good.

Richard Carter - yawn. So what does my 'tax disc' represent then? A slightly pedantic aside to the main issue.

For some reason some here seem to be frightened by motorcycles. The reason I don't cycle much in London is that people don't give you much room - but those who don't tend to be driving cars or bendy buses. It is a rare sight to see a motorcycle rider bullying a cyclist.

I would agree that some bikers do ride irresponsibly - some couriers ride in a way that makes my jaw hit the floor. But they're going to do that whether you allow them in bicycle lanes or not. Cyclists need to play their part too, and not cycle in the outside third of the lane holding up traffic behind them.

I think what we'd all agree on is that the bus drivers need to show a bit more care and consideration to the rest of us!

Richard - if road tax isn't hypothecated but a general tax which isn't re-invested in roads then that explains the state of many of London's potholed roads. (Islington Council take note).

You don't seem to have anything to say about cabs or buses - would you ban them from cycle lanes too? The reason I don't cycle much - certainly not to commute - was largely the behaviour of bus drivers. Every other road user - cars, motorbikes, lorries etc - seemed to have no trouble giving me room, not running red lights and blocking up junctions or generally bullying me into the gutter.

In light of recent events the transport authorities are more likely to cast an eye on the transgressions of cyclists that are seen every day on London's streets. Red lights, one way streets and pavements are not regarded with respect by a minority of cyclists. A minority yes, like a minority of motorcyclists, but it does happen.

A cyclist stopping at a red light uses as much energy to restart as cycling 100m. So long as there are no pedestrians and no other road user is inconvenienced, then there is no problem with going through red, after all, if there were no cars, there would be no need for lights. This said, there are cyclists/yobs who speed through red when there are pedestrians ans this is unacceptable.

Boris is a disaster for London, but voters "wanted a laugh"...

What London urgently needs is a car parking tax, new cycle lanes, people orientated streets where cars give way to all and have restricted and market priced parking and a new mayor.
