I don’t care that it’s EV. I’m just stoked that they’re making an actually modular system like this. I don’t know why it’s not possible with other cars.
It makes sense for a utility truck to be modular. I cant say the same for vans and sedans.
Tesla made some progress with this, but it’s the dealer network. The existing manufacturers are beholden to it and $200 oil changes.

GMC made a modular system for like 50 years, it's called the SBC.
The modularity is there with classic manufacturers too, just not "exposed" to the buyer. Cars use a common platform and you can still buy the classic or fastback, different styling packages, but you won't be able to self service them after the sale. I don't really know how much Slate is the Framework of the auto world, and how much it's just customization options at purchase time.
Most people who buy a car would never be bothered to "tweak" it later, upgrade, add stuff. Modularity also constrains the design and could add some reliability issues.
The biggest benefit would be home repairability so I think that's a big driver for why other manufacturers don't do it. EVs already require less maintenance so that's lost revenue.
P.S. Looking at the options on the site, other than the body style everything else is just as easy to have on any other car. Most of the customization is purely esthetic (wraps, decals, rim options, light plates) and even the practical options like light bars or roof racks are common in the OEM world for any classic brand.
I blame the dealers, at least somewhat. In the early days of the Scion brand, the idea was something like, all of the cars are shipped to the dealer as base models, customers could choose from a menu of add-ons, and the dealer would install them. Want just the basic car? Fine. Want to add keyless entry and mood lighting and a CD changer and chrome alloy wheels? They'll add those for you.
But (at least in my experience), that made for a worse product than having factory installation and QA. I bought a brand-new car from a Scion dealer in 2005 and indicated I wanted to add keyless entry. I paid the dealer, they did the install, and I left ... with a car that would intermittently fail to lock some doors with the key fob. I realized shortly thereafter that the dealer had installed an aftermarket system to save money rather than the offical Scion keyless entry system. I complained and eventually got them to install the right system, but jeez, that did not enhance my experience compared to just finding a car that was built in a factory with the options I wanted.
I'm not saying the modular Slate pickup isn't cool. I'm kind of tempted by it. But I wouldn't be surprised if people find themselves with leaky roofs, electrical gremlins and random squeaks and rattles compared to if they just bought some other truck/SUV and left it alone.
