The main reason those cheaper EVs are not widely available yet is that the more expensive vehicles are more lucrative and the whole market is supply constrained. So, most manufacturers are just churning out big expensive SUVs as fast as they can and are allocating all their battery supplies to that because they make more profit on those. As the market continues to double in size for the next few decades, inevitably, they'll start churning out cheaper/smaller/lighter vehicles as well. Basically, the market is far from saturated yet so that might take a few years. Hybrids have a role in the market for the brief period of time that battery production capacity is not large enough yet to replace them with cheaper EVs. But they are inherently more complex and costly to manufacture and drive. So, that's not going to last long.
