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.
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.
Personally, I’m not bothered by the sounds that EVs emit at slow speeds (the minimum sound is required by the NHTSA) — I think they even sound kind of cool. I do agree that collision detection is also useful. I would argue for a combination of mulitple safety systems. That being said, I do completely understand the noise pollution concerns of vehicles; however, given that the sounds are only emited at very low speeds — IIUC, these sounds are intended match the sound pressure generated by a vehicle travelling at 30kmph — it shouldn’t be too much of a problem; I believe that it is worth the benefit.
