Electric cars have to make noise on purpose because otherwise it would be a silent car. And most of these noises are are weird futuristic WEEEE-00000 UFO sounds. Therefore I posit that we should be able to change the noises our electric cars make
EDIT: These suggestions are Top-Notch! Keep em coming!
Recognizability is the key. That is the entire purpose of the fake car sounds: to have your car make noises that bystanders will immediately recognize as a nearby car. It’s a safety feature. The ability to change it to an arbitrary audio file negatively impacts a safety standard. Same reason why rainbow crosswalks are a bad idea.
Had me in the first half, ngl.
It’s not exactly the same thing, but it is analogous. Taking a standardized zebra striped crosswalk and recoloring it for any reason (pride, sports team colors, etc.) is taking away from that standardization, reducing safety.
It depends what you understand the purpose and effect of a crosswalk to be.
If you think it’s basically a signpost on the road saying “there might be pedestrians here” then the standardization is perhaps important. But even then there’s a decent amount of latitude as long as the feature is recognizable.
If it’s just visual noise that makes people uncomfortable to go fast through, then the specific design is far less important. (“Friction” as described in this video.)
