I'm well aware of the larger torquebands across wider RPMs of electric motors vs ICE motors, especially the high torque available at 0 RPM. But that doesn't change physics or chemistry.
Porsche Taycan isn't a supercar, and it has this high/low gear / Two-speed transmission for its EV, because at higher RPMs even an EV will run out of torque, and it becomes a good idea to convert RPM vs Torque through the use of a gearbox. Gearboxes / Transmissions have been used for a hundred years. They are among the most sophisticated parts of a modern car, and are made with cheap steel and highly automated manufacturing today.
Every motor will have a limit to their useful torquebands. EVs have the widest torque vs RPM in existence ever, but even the biggest motors and biggest EVs have problems.
This is complicated by the fact that Hybrids are far smaller electric-motors with far less battery power than the pure EVs like a Porsche Tycan. As such, the incredibly popular Toyota Prius Prime opts instead for a proper CVT transmission. And I'm willing to bet that Prius Prime 2024 is getting a better driving experience in practice.
Furthemore: there's something to be said about sophistication of dumber / simpler metals. Steel is found everywhere. Trading cheap steel for Lithium, Copper, and Cobalt sounds like a bad idea to me in general. I guess that copper/lithium is lighter than Steel so saving on weight is helpful, but there's some crazy bad environmental problems associated with these rarer and more complex metals.
