I see a lot of people complaining about the undoubtedly stressful conditions at present on London's roads. But I see few people complaining about motor vehicles. Yet in the last 24 hours three vulnerable road users have died after being hit by people driving motor vehicles.

I simply don't understand why we don't ban drivers like this for life. It's a licensed activity, you've shown you can't be trusted to do it, why should we let you ever get behind the wheel again?

Pretty sure it flapped open a few times going over potholes. Happy with my normal phone and a generations old but very cheap second-hand once-high-end tablet now. Crap processing power, great screen: good for reading, but not much else.

I loved my OG pixel fold: the "tablet in your pocket" thing is so useful for reading books, articles, comics etc on a whim. Even just showing photos on a slightly larger screen. Obviously nice for watching videos too. Sold it because I didn't like the peril of it strapped to my bike's handlebars.

If drivers always respected each other, we'd not need traffic lights. If they always respected pedestrians, we'd not need zebra crossings, etc.

Leo McArdle 🇺🇦 @leo.mca.is · 17/09/2026
In my mind that's not excusing, I guess in yours it is, maybe it doesn't matter. My point is we can't rely on people to behave properly and considerately all the time: if we could, we'd not need any infrastructure or rules at all!

In my defense, I did have to frequently look back to the cycle path to check for pedestrians walking out in front of me, so I probably missed a few!

Leo McArdle 🇺🇦 @leo.mca.is · 17/09/2026
Where have I excused that? Please tell me! I've repeatedly called for more considerate cycling! People have spent 3 days now telling me I'm doing that, but can never point to when or where! Pointing out that cyclists *shouldn't* have to, in an aspirational world, isn't saying it's ok!

No automated cameras for catching handheld phone use while driving though, as far as I know. Also illegal. Highly dangerous. Incredibly common (saw 6 definite uses, and about double that possible uses, on a ~1hr cycle yesterday - not to mention the guy who close passed me while doing it!)

Leo McArdle 🇺🇦 @leo.mca.is · 17/09/2026
No, it's an aspiration. Pedestrians should be able to walk across cities with very little need to stop. Then bikes. Then buses. Then cars. All too often its exactly the opposite way round.

As a cyclist, I'm sure you've encountered many junctions where you've got a red light for no discernable reason. Or, simply, just because some car-brained traffic engineer decided you weren't worth conveniencing. This is bad! This should change! This is what I'm arguing for!
100
Leo McArdle 🇺🇦 @leo.mca.is · 17/09/2026
I'm not sure what policy levers we have for solving that, aside from changing the built environment which encourages such prattery. I'm not defending or excusing poor cycling - I've spent 3 days now saying cyclists should be considerate - but the way to ensure that is good infrastructure!

Leo McArdle 🇺🇦 @leo.mca.is · 17/09/2026
Sorry, but can we not do what? The point I've been trying to make - and I think at this point, is being wilfully misconstrued - is that by and large the behaviour of cyclists is dictated by the infrastructure and rules they have to contend with. Even if we do just decide that some are prats,

Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
I've been called all manner of unsavoury things trying to tell drivers this while they're blocking one. Get a lot of bemused looks from the pedestrians dutifully walking around the car as well...

Unsurprising people are irritated. Cyclists are not responsible for the bad behaviour of other cyclists any more than drivers are. But they do feel exasperated by the endless ‘othering’ & media attacks on a mode that is incredibly low risk, in the context of 29,000 annual UK motor vehicle casualties

I managed to set off an illuminated "20 slow down" sign earlier today, which was fun. Or it could have been the motorist speeding to overtake me... Let's go with the former, it makes me sound more athletic!

Virtually every time I try to cross busy main road, this happens. Far more dangerous & less accessible than a bus stop with a cycle track, & happening everywhere. Yet no moral panic & media hysteria.
Car stopped on crossing when green man is showing for pedestrians- usually they will move off as soon as there is space even when crossing still in pedestrian phase.

Suggested ground rules for the ‘debate’ on 'bad' cycling 🧵: 1) Cyclists or cycling advocates are not collectively responsible for the bad behaviour of individuals. What’s your actual point? You want less cycling or rules that have that effect? Be clear.

You literally said the cycling community. If all cyclists aren't part of that community then who is? And where am I arguing for the license to be a prick?! Please tell me, and I'll retract that statement, and profusely apologise. But I'm not! I'm arguing for considerate cycling!

How about we resolve to come back to this thread in 50 years and see how the law and infrastructure has changed, and if it's closer to what I'm arguing for, or what you are? If motorists are still prioritised above all else in our cities then that's a grim thing to aspire to. See you then!

That's not, no cyclist should ever have to wait for a red light though, is it? That's no cyclist should ever have to wait for a car! In a city! (Though this later turned out to be on the outskirts, so maybe the calculus changes?) Just as no pedestrian should. Zebra crossings everywhere!
000
Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
Of course we need to wait for pedestrians. I do, all the time. Even when I'm not obliged to! That's what I'm advocating for! Protecting those more vulnerable in the hierarchy.
000
Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
No! I'm saying if cyclists do jump red lights- especially when *they're* the most vulnerable road user, which is the case in this situation - then the reason is probably poor infrastructure, rules, etc. Or at least, it's the only real lever we have to pull to make things better.

Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
It's not! Do you want to point out where I've said that?

Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
Ok but for many that's how they access cycling, it's a de facto ban. And we know it takes very little to discourage people from cycling (look at the evidence around helmet mandates). It still seems excessive!
200
Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
Do you maybe want to address the questions, or just mock/shame me? Why should we prioritise motorists needs above cyclists and pedestrians? I'd say the same thing about pedestrians. I wouldn't blame the victim if they're hit, even if crossing on red!
100
Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
A permanent ban seems a bit excessive, no? For just swearing at someone: not even hitting them! We don't apply that same standard to drivers. Maybe we should!

I beg you read what I - and other cyclists - are saying, and not just make it up.

Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
Banning seems a bit excessive, no? Unless we start banning drivers on their first offense? Actually I could support that!

Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
Sure, and I do! And I've apologised to Rachel repeatedly for being hit. I've said the cyclist was wrong. But if we start talking about policy (which is what I originally replied to), then I'm gonna talk about policy!

Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
That explains it all. You're an experienced cyclist. A lot aren't. Most killed aren't! And everyone not currently cycling, who we need to encourage to do so, are by definition inexperienced. We need infrastructure and rules which respects and understands that!

No the road signs weren't designed to protect them, they were designed to convenience motorists. That's my entire point!

Victim blaming.

Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
I was disagreeing with (what I thought your point was), roughly saying "motorists don't get absolved from blame when they hit people". They do! And they don't think they're in the wrong! And the justice system either doesn't punish them or gives a light tap on the wrist!

Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
You're gonna blame the victim in that situation?!
100
Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
Yeah, because they're the more vulnerable road user, in the same way I'd excuse a pedestrian getting hit if crossing on red. We should all do our utmost to protect the vulnerable, even if they're being idiots! Idiots deserve safety too!
100
Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
What do we do about that, then? Shame? Arrest? Detention? Or should we let the evidence lead the policy interventions which will make streets safer for all?

Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
Bloody hell mate, I don't think you can be trusted to read what I was replying to. This was a car-on-bike collision, no pedestrians involved.

Leo McArdle 🇺🇦 @leo.mca.is · 16/09/2026
I agree! Cyclists shouldn't cycle aggressively. I don't think it's anywhere near as many doing so as the vibes make it feel like - but, sure, a lot of that is vibes on my part! (And the evidence which shows most pedestrians hit and injured are by motorists.)
