Is the CPM assertion supported by data? Does it factor in incentives at the federal level that are subject to sunset provisions? Does it include local incentives that are inconsistent when looked at across the entire US? (ie: CA vs TX) Is it utilizing a normalized cost structure for maintenance (hourly labor rate, for example) which is also highly variable geographically?

Data is based on cost of electricity versus cost of gasoline. EVs have only a handful of moving parts compared to internal combustion vehicles, so maintenance is less overall (battery coolant and brake fluid changes ever 2-4 years, cabin air filter every 1-2 years, tire rotations every ~6k-7.5k miles).

The US is a bit dysfunctional compared to Europe (where they put a priority on shifting away from fossil fuels with subsidies and taxes); regardless, even a Tesla Model 3 without federal incentives (which finish phasing out for Tesla shortly) is still cost competitive when total cost of ownership is evaluated against most internal combustion vehicles (except hybrids).
