During 2013–2017, casualty rates per 100 million miles were 5.16 (95% CI 4.92 to 5.42) for E- HE vehicles and 2.40 (95%CI 2.38 to 2.41) for ICE vehicles, indicating that collisions were twice as likely (RR 2.15; 95% CI 2.05 to 2.26) with E-HE vehicles. Poisson regression found no evidence that E-HE vehicles were more dangerous in rural environments (RR 0.91; 95% CI 0.74 to 1.11); but strong evidence that E-HE vehicles were three times more dangerous than ICE vehicles in urban environments (RR 2.97; 95% CI 2.41 to 3.7). Sensitivity analyses of missing data support main findings.

Not surprised they suspect it’s noise related. However, I’m all for reducing noise pollution. Not for having cars overcome background noise to become noticeable.
One thing to note is that no matter how quiet the motor on a car is, the tire/road noise is still the main contributor unless you have an obnoxious exhaust system.
That is probably true most of the time but there are a few factors that come into play just for tire noise: type of tire, type of driving surface, and speed of the vehicle at least. In the city you shouldn’t be going fast enough to guarantee tire noise is the biggest factor.
Though, for EVs I’m assuming that has to be true since they make practically no noise otherwise.
More pedestrians are injured in Great Britain by petrol and diesel cars than by electric cars, but compared with petrol and diesel cars, electric cars pose a greater risk to pedestrians and the risk is greater in urban environments.
I don’t understand this statement. More pedestrians are injured by gas cars but electric cars are more dangerous?
One plausible explanation for our results is that background ambient noise levels differ between urban and rural areas, causing electric vehicles to be less audible to pedestrians in urban areas. Such differences may impact on safety because pedestrians usually hear traffic approaching and take care to avoid any collision, which is more difficult if they do not hear electric vehicles.
This makes some sense. My car is just a hybrid but plenty of times I’ve had people just slowly walking in front of me in a parking lot. They can’t easily hear my car at that lower speed as far as I can tell. And full electric would be even quieter.
It’s interesting though. No easy solution is immediately coming to me, other than pedestrians getting more and more used to cars not making any sound.
More pedestrians are injured by gas and diesel cars because most cars in the UK are gas or diesel.
The UK has less EVs, but they injure pedestrians at a higher rate than gas cars.

If I understand it correctly, the reason is because there are more ICE cars than EVs and H-EVs. In absolute numbers, this makes it so that ICE vehicles collide with the most pedestrians, but, per vehicle, EVs and H-EVs collide with the most pedestrians.
No easy solution is immediately coming to me, other than pedestrians getting more and more used to cars not making any sound.
I’ve heard some newer EVs and H-EVs emit sounds (usually some sort of whirring sound) to alert pedestrians. Keep in mind that the data in this study was from 2013-2017. There have been some innovations made to mitigate this issue since then.
We have “whistlers” to supposedly give the deer/other animals warning a vehicle is approaching, maybe add a speaker system that just makes ICE sounds
Ideally we would be able to keep the benefit of quieter streets and parking lots though. Maybe there’s no getting around it
Wait, are the cars themselves are twice as likely to hit pedestrians, or are the drivers of the cars twice as likely to hit pedestrians?
Website is not working. Do they make any speculation? What’s the sample size?
Which link isn’t working? I linked the PDF from the source and an internet archive alternative. They both seem to work for me.
