[AmpsterMan]

Stroad is a word that has increasingly come into popular use and is well defined.

https://en.m.wikipedia.org/wiki/Stroad

You can ignore new terms if you wish, but it is useful for describing a common street pattern in North America. The term is increasingly being used by urban planners.

We already had a term for that, a four lane, and "street" and "road" are synonymous so combining them doesn't produce new meaning

The only people who use that word are insufferable choads who want me to give up my car and live in a tiny apartment because of their misguided belief that if everyone lived like they do in Manhattan global warming would end and the world would be a Utopia

"Stroad" is a shibboleth that tells me you're someone with an opinion that is not worthwhile

They’re not exactly synonymous though, at least most dictionary definitions differ.

Street example[1]: a road in a city or town that has buildings that are usually close together along one or both sides

Road example[2]: a long, hard surface built for vehicles to travel along

A street in this case is a type of road. A stroad is another type of road (where buildings are not “close together”, f.ex.)
