Zefal Universal Smartphone Adaptor Bike Kit

I can do all those things while driving my car too! But I'd be distracted and steering with only one hand while driving my 2 ton SUV. If you think cycling one handed while trying to take a call is OK then good luck to you.

Just remember that when you remove even one hand from the bars you have less control add-in a distracting element like a phone then you're as bad as those drivers who do the same.

Genuinely trying to work out if you're for real or having a laff, conflating operating a 10kg bike with one hand vs. a 2,000kg car, being equally 'as bad'. 

...if you are for real, I suggest you *NEVER* watch any pro cycling, or visit Amsterdam, or in fact pretty much anywhere cold, ever - it's likely to kill you with apoplexy at the sheer reckless avalance of one-handed riding. Oh, and I recommend a read up on the laws of physics, mass / velocity / energy, etc. 

...also, you seem to be condeming anyone with only one functional arm to never cycling. Nice. 

Cheers

And don't forget the one handedness required when signalling.

I'm not saying that both are equivalent but you state that using a phone is "perfectly safe". I am just pointing out that many drivers used the same argument when using a mobile phone. You can't be in full control of your bike while riding one handed (those with a disability would have adaptations to allow them to have better control). I was just presenting the argument to you. While the consequences of a loss of control is likely to affect you rather than anyone else, it's not a good look when we are trying to get car drivers to give us more respect.

We argue that hands free sets in cars distract drivers but it's ok for us to make a phone call when riding on a public road? That would strike many motorists as being a double standard. 

We don't live in Amsterdam or any those other places you mention, our roads are rough, full of potholes, speeding cars and heavy trucks. The pro peleton again isn't facing the same issues although there has been more than one accident when  a pro has taken their hands off the bars.

p.s. hold a first class degree in Physics so know all about mass, velocity but thank you very much for your concern about my mental ability.

It is clearly not 'perfectly safe' due to cognitive overload, however the cyclist will suffer but unlikely anyone else will

Your words, not mine: "you're as bad as those drivers".

Let's clear up a few things here shall we? 'Cognative overload' in this context is nonsense. I'm removing a phone to then press a button to take a photo. I will have naturally slowed down to suit the terrain/conditions, and also to reduce blur. There is no more 'overload' than trying to shift gears whilst thinking about what to eat next. Also, I can be having an inner monologue with myself about eating/drinking too much last night, or chatting with a friend about the foibles of gear cable outer selection and be using up far more brainpower than moving my right hand to take a picture. You've got no science on this, because using a phone to take a photo on a bike is a non-issue. I'm not trying to solve a quadratic equation or proof-read a dissertation on 14th century crop rotation. Likewise I'm not reading or sending text messages or social media posts whilst moving at 60MPH.

And your 'we are trying to get car drivers to give us more respect' victim-blaming collective-responsability nonsense shows just how far, far behind the curve you are, and how little you understand the issues. I take zero responsibility for anything you do just because you do it on two wheels, and I utterly reject your assertion that I'm responsible in any way for anything that happens to you. In asserting collective responsability you're no better than those who use it as a bigoted tool to hold back publicly-funded improvements to cycling infrastructure 'until cyclists stop breaking laws'. My derision for such views - held by people who ride or not - knows no depths, because the consequences of pandering to said views is that people die for want of said infrastructure. 

ps it's a photo, FFS, and I hardly ever ride on public roads these days. I'm all about the Gravel. 

You skipped over the using the phone for calls. Plenty of research on cognitive overload on that. I'd suggest your inner monologue can work in the same manner and you will tune out of your surroundings.

Look OK OK for all the pedants out there: It's a bloody stupid thing to do, answering a call single- or double-fisted whilst descending a 20% hill in the wet whilst shouting at mothers with prams to get out of the way of the oncoming HGV. 

My specific statement was, relevant to taking photos or answering a phonecall: '* yes you can do all of these things in perfect safety'.

And this is true. You can. Pick your time, place, speed, surface, surroundings. do I really need to clarify 'can' as opposed to 'must' or 'should' or 'always will'?
