Nope. Notice the number of models on the chart has gone from around 160 to 260 - and that the chart only goes through 2019. By that time there were, at best, a dozen EVs on the market, and perhaps a few more hybrids.
The models keep multiplying because consumers have varying needs and tastes, and automakers are serving them. In the past decade three distinct segments have appeared just in the pickup market. There are the “cute” pickups, like Toyota and Honda for the suburb and homeowner market, the mid-range (where the sweet spot is right now accounting for about half the segment) and the large pickups like the F-150 and similar, good for towing, contractors, farmers, and so on. The profits in the segments were so distinct Ford announced it was leaving the midrange segment a few years ago for the high end (it has now announced it has a new entry ready for the middle).
Vans have two segments, and have had for a while: the Mommy van with lots of seats or space, and the commercial vehicles used for delivery and plumbers and electricians and the like. That’s actually a decent size market, and you’ll pass 20 Mommy vans just running to the grocery store on any given day.
There is no reason why these customer needs will disappear just because the drive train changes - and the argument is the same for all the various segments of strictly or mostly passenger cars.
A Subaru SUV is vastly different from a Yukon because there are discrete market divisions even within the SUV class.
Well, at least I’m glad you’ve accepted that all cars won’t end up looking like toasters. That’s some progress. I can’t help but notice you left out “sedan”, which happens to be the best selling car on the market today (Tesla), so you’re thinking Elon is going to abandon this segment?
(You’ve also accepted, I guess, that “hoods” won’t disappear in favor of the toaster form factor, given that they provide aerodynamic heft and a decent place to store, uh, energy or engine or something . So you’re coming along. Congrats!
Software tends to commoditize - it does the same things, just different ways. An Apple and Android perform nearly all the same functions: phone calls, games, video, music, etc. but with different execution. But with a car the primary function is: driving, (transportation). You’re thinking I’m going to buy a car based on which one brakes better because the software tells the regenerative brakes (or disk pads, or whatever hardware implementation it uses) to do it better? I don’t think so.
Self-driving might be one such feature, but then it will either work or it won’t. If KIA has it and Toyota doesn’t, that’s a clear differentiation. If they both have it they will be close to equal - and therefore not a strong point of differentiation.
Microsoft and OS, same but different. Android and iOS, same but different. C# and C++, same but different. Software is the invisible layer which facilitates certain options, but it doesn’t change the hardware, and hardware is what differentiates the auto market. That’s not gonna change, period, ful stop.
