I was going to make fun of this, but realized I’m not blind - if some who is could tell me how much they depend on sound of a car to determine safety is really appreciate it.

[edit: I vaguely recall seeing a show that said the primary source of noise on the highway at least was due to tires on the road rather than engine noise]

I am blind and depend on the sound of cars a lot. When crossing busy streets I listen for traffic patterns to let me know what light is green and red. On less busy streets I listen for individual cars. There are not a lot of electric cars around me so I don't have any first hand experience on if tire noise is enough.

I don’t think tire noise would be enough at low speed (I mean I’ve heard cars with very load wheels+suspension but I suspect that wasn’t by design).

It was intended more for the context of making highways quieter, for that you need something more complex - it’s things like the sound of the tread itself hitting the pavement etc
