Twenty-eight companies in the electric vehicle industry, including big names like Tesla, Lucid, and Rivian, have joined forces to create a new organization called ZETA, with the goal to push for 100% electric vehicle sales by 2030.

"but if lucid was also a 2 seater lets assume it would be half the weight, lets assume that means twice the kw/mile" As kiteboarder said, losing two seats doesn't change the weight that much, I would estimate 20% at most. Plus with good regen, weight is much less (80-90% less) important for efficiency than in an ICE car. Aptera is a two seater (plus long hatchback) because that fits the aerodynamically optimal Morelli body shape (and also so that they don't overload the single rear wheel). At low speeds, all the EV's are more similar in power usage, but the Aptera will stand out at higher speeds.
