They aren't necessarily all scrapping everything EV.

Ford for example wasn't making money on their current EVs, and they realized they weren't going to make enough money on them as designed so they started up a new program to build an EV from the ground up that can be profitable.

But they incurred billions in losses on their current offerings. Those losses do include learning though, so while the dollar losses are huge, the new EV program wouldn't have the same knowledge base to work off of if they hadn't done those first EVs.

So they're writing those losses off, in the interim looking more at hybrids, while also still pursuing their new EV platform.

It's still the wrong move IMO, they're going to fall further behind by doing this, and the learning will slow, and there's still no guarantee that the new platforms will be on time / profitable either possibly delaying things even further.
