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.
Damn that is a huge effect size… I am shocked, especially given safety features that now exist on newer cars (unless they normalized for car age).
Do note that the dataset that they used is from 2013-2017.
Interesting. When did they start adding noise to low speed EVs? I wonder how this analysis would look for newer vehicles.
At least 2016 (in the USA) [source (archive)].
Put a bell on them, works for cats.
I’ve never been struck by a cat in a crosswalk so this suggestion checks out.
This is why I want an electric car that makes a jet turbine noise like the cars do in sci-fi movies.
Anecdotally, I’ve heard some newer EVs emit a sort of whirring sound when they are moving slowly to alert pedestrians.
I have heard this as well. IMO it’s much too quiet still. I want like, an actual jet engine whine but at maybe 65-70 decibels.
No thanks, electric vehicles being quiet is a bonus.
Now if they had the forward sensors made a moderate lebel honking noise when a potential collision with a oedestrian is detected, that would be great.
EVs being quieter than ICE cars is a blessing imho. I’m not completely against having them emit additional sound for safety but please let it still be quieter than an ICE.
So you don’t want a 126db electric car?
