"Accident" implies a lack of blame. The vast majority of vehicle "accidents" are not.
If you're speeding to pass someone and hit an oncoming car, that's not an accident.
If you're impatient and try to squeeze by a bicycle and hit them, that's not an accident.
If you're texting on your phone and rear-end the car in front of you, that's not an accident, it was a conscious decision.
If your transmission seizes or your wheel fails off so you fly off the road into something (and you haven't been ignoring maintenance on your rust bucket for so long that you should expect this), that's probably an accident. But that's an infinitesimal fraction of vehicle incidents.
Stopping the deliberate debasement and pollution of our language. That's what I'm gaining. Or trying to.
Call it what it is ("traffic accidents"), and we can stop arguing. Other countries have fewer accidents? OK, that's worth talking about. I didn't "miss the nuance" because I'm not responding to that right here.
Or "bad road engineering" if that's what you want to talk about.
Language is living. Get off your high horse. People are allowed to invent and use new words and terms. Language evolves with use, not by people like you holding on to dear life for every little thing.
Inventing inflated words to make something old sound like a fresh crisis is indeed debasement and pollution. I guess you don't know or care what that is.
So don't tell me what to say. You can keep doing it and I can keep calling it out, and there isn't a thing you can do about it.
