There are, with the federal government alone paying 7k on most EVs sold in the US. The problem is that they are neoliberal flat subsidies applied at the point of sale that needed Republican support to enter law and as such companies just tack on 7k to the price customers are willing to pay anyway.

What we need is to incentivize manufacturers to focus on bringing down costs by focusing on things like LFP batteries and smaller vehicles, but manufacturers are currently incentivized to make larger vehicles because people are willing to pay a lot more than the added space cost to make, thusly increasing margins. At the very least making the full subsidy only available on vehicles under 25k, with a decreasing subsidy for vehicles under 50k would probably help, but you would need to be ready and willing to call manufacturers on their near certain attempts to get around it.

Some actual price wars between manufacturers would help too, but US auto manufacturers will fight tooth and nail to forestall that possibility.
