Alex Dowsett breaks collarbone

@chrisonabike I agree that PPE is always the last line of defence, and having safe systems is always more important. But I'd say that being visible is still very useful in a lot of locations where effort has gone into safe systems (like railway tracks). Proper H&S 'hi-viz' will include reflective bits appropriate to the work and setting. What's right for improving visibility while cycling will depend on when you are cycling, where you are, what conditions are likely. What Heidi is wearing looks adequate to me, assuming her full route is in good light. I don't know much about the Reading end, although I'm sure I spotted a segregated cycle path, but London has a lot of good routes, and crucially, most drivers there know to expect cyclists. Her block of bold red will stop her from blending into the background, and as that's the bit of her that's moving, that's a great way to help the subconscious brain notice there's a human up ahead. Her hair, feet and sandals are all light, so help to catch the eye against dark backgrounds. I suspect the light coloured rim of her helmet is reflective, and I've got spoke reflectors and stickers on my bike, which is an easy way to add reflectivity regardless of what you are wearing. Particularly useful in Winter when there are a lot of competing lights. I favour using running lights all year to keep me a bit more visible when going through areas of shade and in the hope drivers will register that there is a bike ahead. But I also live in an area where most drivers are not expecting to see someone cycling, so it's more important to announce yourself here than in London. Anyway - good for Heidi. The complaints about not wearing hi-viz will only help to get the video seen by more people, and a great reminder that cycling isn't just for men in lycra.

Could we get some updates, the glove world hath changethed.

Google is broken. Even if they are forced to roll back on the made up summary (a German court said it was original content so they're liable), it will still be a front page of SEO slop. Images full of geometry nightmares. Another vote for switching search to DuckDuckGo. You can turn all the crap off in Settings. Ah, bliss.

Famous last words: We're safe from leopards up here.

If you're not trying to escape from wild animals, what would be the advantage of putting a tent on top of a car, rather than setting up a similar tent on the ground? Seems rather unnecessary to me - even if the price was comparable, I would choose a ground-based version.

V v tempting.

"you can’t pass a law saying it’s illegal not to have a speedometer if you’re going to go above the speed limit." I don't think this would be a good idea, nor even speed limits (and presumably mandatory speedometers everywhere) ... ... but is there any theoretical legal impediment to that? Or even simply enacting a law that cyclists are not permitted to ride faster on roads than the motor vehicle speed limit (or some other limit) and leaving it up to cyclists how they go about complying with that? (Not a lawyer not a legal theorist though...)

What has KE to do with it? If you are hit by a large object you don't absorb all its KE. Being hit by a car is no better than being hit by a bus at the same speed. What matters is how much acceleration you experience.

@Robert Hardy 20mph isn't as fast as you seem to think, this 57-year-old-not-that-fit rider can easily achieve it on the flat in still conditions and most averagely fit people can on a decent bike. The argument that it wouldn't be a problem to impose speed limits on cyclists because those who can achieve 20mph already have speedometers is an entirely specious one, firstly as I've said a huge number of people can achieve 20mph, not just Garmin-obsessed racers, and secondly you would have to make speedometers compulsory for everyone on a bike, you can't pass a law saying it's illegal not to have a speedometer if you're going to go above the speed limit. How many cycling incidents are caused by supposedly excessive speed? It wasn't a factor in this case, the cyclist would still have hit her if he'd been doing 15mph or even 10mph. Charlie Alliston was under the car speed limit. It's a non-issue and only of interest to those seeking yet another stick with which to beat cyclists.

(Usual reference to speed being the major issue as kinetic energy goes up with the square of velocity / much greater braking distances required etc)
