There's a bit of an illusion here because gas prices take into account a tax for road maintenance, which EVs are currently avoiding. Eventually the system will have to catch up because road maintenance requires money.
While electric vehicles do cause more road wear, applying that tax to most consumer vehicles is the joke. Road wear is completely dominated by semi-trucks.
The simplest method is to raise the HVUT, but we have so much data, we could assess miles driven * axel weight and charge a graduated fee based on that.
