Why is there this disconnect between attitude towards speed and speeding behaviour?
A study I ran just over 10 years ago looked at people’s reasons for driving unsafely including why they drove over the speed limit.

Despite stating speeding is dangerous, only 3% of the British public state that they themselves are dangerous when they speed.
Overconfidence means people tend to view the rules about motoring are there for other people and not there for themselves; some people feel they are so safe at driving and so experienced, that they themselves can determine a safe speed and choose to speed if conditions allow.
The road is a social situation, people mimic and imitate what they see around them, they are influenced by social norms.
People tend to believe others are speeding, and as such speed as well.
People may easily fall into habits and norms of speeding, or even fail to notice that they are speeding themselves.
Some people use the car to show off and show that they can speed, some performing to “type” (boy or girl racers for example), some impressing friends (especially young male friends). 
Overall, there was a feeling getting caught for speeding just wasn’t really that important; a case of bad luck rather than bad judgement.

Another research project I was involved which looked specifically at 20mph and suggested people had concerns with actually being unable to drive slowly without using a lot of fuel or polluting the environment, with cars not being geared up (literally) to run at such “slow speeds”. In addition, some drivers felt a lack of attention to other road hazards occurs when driving slowly; a real life example of risk compensation. Some drivers though, managed to drive at 20mph, these champions and leaders responded well to the safety argument in particular, and stood up for their decisions even when tailgated from behind. The majority though, fell in with others’ speedi…

People are used to the optical flow sensation of scenery rushing by at a certain speed, that when they travel at a lower speed there's dissatisfaction.
"negativity among the public + drivers, actually falls after implementation, when people’s worst fears are not realised and a new norm is formed."

2025-2026 Webcast Series, Ep 4: Safer Streets for All: Protecting Vulnerable Road Users | UKROEd 11am BST, Mon 30 March. James Luckhurst presides over a fascinating debate on protecting a wide range of vulnerable road users.

Took part in a @ukroed.bsky.social webcast on “Safe Streets for All” discussing vulnerable road users, underreporting, and why lived experience matters as much as data. Safer streets start with those most at risk. Watch here: www.ukroed.org.uk/ukroed-media...

Why has the 20mph limit become such a political issue in the Welsh election? Political parties are lining up to talk about where they stand on the 20mph urban speed limit in the Welsh election campaign.

Is the 20 mph speed limit debate coming back for Wales’s Senedd election? New post by me & @charliemuss.bsky.social for @theconversationuk.bsky.social discusses the what and why.

New piece in The Conversation: Wales’ 20mph limit became political and still faces backlash despite collisions being down. My analysis of X also shows public mood becoming more positive over time. Evidence + sentiment both matter. 🚦

Don’t expect your car’s safety technology to save you What if ADAS is just for convenience?

I wrote this a couple years ago, warning that car safety tech will never be a panacea.

A big reason why: Drivers take more risks when they assume technology will protect them if something goes wrong. It's known as the Peltzman effect, and it's really bad news if you're walking or biking.

I'm at a #TRBAM session about car tech (AVs and ADAS).

@iihs-hldi.bsky.social head of research says ADAS leads people to drive more dangerously, negating its crash avoidance potential.

A reminder that safety tech can look a lot less useful when you consider human behavior changes.

One of the best write ups I’ve read on road safety claims by AVs.
We’re not comparing apples with apples human driver v AV.
And remember:
“Self-driving technology is only one of many tactics available to reduce crashes, and it is not at all clear that it offers the highest return on investment”

Towards a research agenda to better understand the role of walking for healthy ageing and wellbeing in African cities

New paper out with Carlo Luiu in Journal of Transport & Health. We call for a new research agenda that treats walking as health care and streets as spaces of care for older adults in African cities.

This is a good point. I found 88% of older people didn’t walk at the DfT required speed of 1.2m/s (no one knows where that figure comes from by the way - think it’s a 1950s MSc diss from the US) (I didn’t look at blackout period) see more www.drcharliemuss.com/crossing-the...
