Also from what i have researched myself LFP is a great battery tech, but based on energy density it is not really suitable for universal EV application (Heavy weight, lower range x2 from lower energy density and extra weight), so this would work only for a very niche EV application (Such as 50-100 mile city hopper).
But I think if made to free market and depending on a price, an short range "hopper" EV with LFP battery that looks like a conventional car (Honda Civic for example) with NON of the "smart" features would be a great 2nd/3rd car application, of course this would only apply to the proverbial "rich" since usually they are the only ones able to afford 3 cars anyways. This is why it has to be free market and let the free markets decide
The Plug-In Hybrid on the other hand would be a great application of this (The battery must be made much much smaller), but it needs to be "dual use" - charge from plug in, but also charge from engine if needed.
