At first it was a trickle, now the numbers of law abiding cyclists seem to be in the minority.

The flouting of traffic laws by cyclists is causing a real danger for pedestrians both at road crossings and on the pavements as well. It’s also frightening as a motorist – who wants to run a light-jumping cyclist over on the way to work? Not me.

The situation is so bad now that cyclists yell at pedestrians on the pavement to “get out of the way”. Any complaint from the pedestrian is generally met with verbal abuse.

It’s reassuring to know that Mr Cameron is leading by example.

For a start, far fewer people cycle where helmets have been made compulsory. Since cyclists tend to live longer and be healthier than non-cyclists, reducing the number of cyclists is a tad counter-productive.

Secondly, there’s some evidence that drivers take more risks when cyclists are wearing helmets (e.g. drive closer).

And in the event of a crash happening, there are fairly few accidents where a cycle helmet helps (and may be some where wearing a helmet results in you being more badly injured than if you hadn’t worn one).

But if you do want to cut accidents by making the wearing of protection compulsory, you should start by making elderly pedestrians wear helmets and padding: they’re more at risk than cyclists.

If he doesn’t wear a helmet and gets brain damage, then that is his lookout. The rationale behind the compulsory wearing of helmets and seatbelts is not to protect people from themselves but to keep down the insurance bill, and I am all for it.

Jon @ 1 seems to forget that Cameron was once an “ASBO kid” himself, when he was a member of the Bullingdon Club. Except that it has always been perfectly OK for toffs to get drunk and throw up all over the place. It’s only wrong if working-class kids do it.

Sadly the concentration on “you must follow the rules, regardless of how sensible they are in a given situation” at the expense of “be a good citizen, be aware of others around you and how your actions affect them” is one of the less positive trends of modern times.

Stopping a bike a foot or two in front of the stop line at lights is often good practice to make sure drivers see you (most cycle accidents happen at junctions – positioning yourself to be visible to other road users is important).

I don’t know about the other offences, but the story sounds a bit overblown to me. How many MPs, if secretly followed by a journalist, wouldn’t commit a single traffic offence? No speeding or illegal U-turns?

I don’t think that cyclists should break the law, but when I see roads, and even cycle facilities, designed in such a way as to make it difficult to cycle safely and legally, I start to think that there’s a responsibility on both sides.

There seems to be a bit of “my enemy’s enemy is my friend” going on with cyclists. I hate gas guzzling motorists as much as the next man, and support much lower speed limits in urban areas – this does not however mean that cyclists aren’t endangering themselves and other road users on a daily basis by their utter disregard for the law.

I watch cyclists run the lights in front of moving buses on the junction at the end of my road almost every day. Obviously the threat of imminent death isn’t enough deterrent, so we need to do something else. Throw the book at Cameron and make an example of him.

For someone like him who should be a role model to be filmed doing this is a disgrace. As I understand it failure to stop at a red light is a motoring offence be you on a bike, a car or a 10 tonne Truck.

Put simply the Tory party leader should be prosecuted as a warning to others to obey road traffic instructions

I believe not and neither should it be. Cycling ‘offences’ like these are barely offences at all. A much larger issue is the dangers cyclists face daily from dangerous driving of cars, vans et cetera.

Has listened to Norman Tebbit’s advice about “Getting on his bike” and he is obviously a member of the “No Turning Back” group.
