Simpler yes, but potentially more dangerous. It's easy to lose sight of the fact that electricity can kill you awfully damn fast and without any warning. This is usually not a problem for hobbyists because the total amount of energy in a typical battery is low and the internal resistances are high. But when you're powering a vehicle, especially a high-performance vehicle, those usual safeguards are intentionally removed. So caveat hacker. Caveat mucho.

Also, LiPo batteries can explode if you're not very careful with charge and discharge discipline. Even the small ones in cell phones can do significant damage that way.

Hopefully we will get to a point where we have an LSx of electrical drivetrain. Something that is cheap, powerful, ubiquitous, and easy to install.

Right now though we have some disappointing (from a power perspective) electric drivetrains from Prius' that can be swapped or a powerful but DRM'd Tesla drivetrain that is more work than it's worth.

Well until someone builds millions of pickups and vans with the same EV drivetrain we're not gonna have an LS of EVs. The reason people like the LS is because it's everywhere and cheap. Everything else follows that.
