I wonder if in a few decades the electric cars of all manufacturers will be referred to as "Teslas" the same way most salted crackers became "saltines"?
I get the analogy, but I dont think "saltines" is a good nominee for this type of thing. No one I know here in California says "go buy some saltines" when talking about crackers... we say "crackers". I get that sometimes these things are regionalized, but there are definitely some of these that are likely national.
I was having a conversation with my wife about these type of brands, and ended up looking it up. They are called "generic trademarks"
Generic trademark - Wikipedia
Things like
Band-Aids
Aspirin (used to be a brand name)
Vasiline
Escalators
Kleenex
Velcro
Back to thread topic, since cars tend to be heavily identified, I am having trouble thinking of any car make or model that has become generalized in the way that "Band-Aid" or "Velcro" is. I can think of some cars where the model is more identified with the car than the make, like "Mustang" "911" "3-Series" "Camry" "Accord" "S-Class"
Anyone that found their way online and is reading those names above likely got a picture of specific models in their head reading those names, and knows who makes each one. I dont think "Tesla" will become generic for "EV" though. I do think that "Tesla" will become generic for ANY tesla, and the specific models will not matter as much. This has already happened. This already exists with other brands, as most people see "A BMW" when they see one, unless they are into cars.
What will happen, and continue to happen, is any other car manufacturer who is making EVs will have their car compared to "Teslas".
