Having it scale with price could let a company sell a Smartfor2EV for $80,000 just to get more for it.
Having it a flat rate makes the discount more attractive the closer the car price is to competitive vs other cars of its size and capability.
There are plenty of ways it could be improved but scaling it with price with no regard to any other metric would be a mistake.
Scale with EPA range.. encourage manufacturers to improve the efficiency and technology. You can build a 250mile EV for the same price as the other guys can build a 150mile EV, then you get to chose between undercutting them, or pocketing higher margin.
