If you would be using it just locally, as opposed for road trips, note that it has an LFP battery. LFP batteries are perfectly happy to be always charged to 100% and discharged down to 10% (lower is OK but most people want to keep some spare in case they aren't able to charge when they expected to).

Lithium nickel batteries suffer accelerated aging at high charge and at low charge, so it is usually recommended to stay in the 80-20% range, only going to 100% shortly before a road trip.

A Slate with a 200 mile range operated 100-10% would give you 180 miles between charges. That would be the same range as a lithium nickel battery EV with a 300 mile range operated 80-20%.

What are your use cases that need more range than 200 miles? I used to drive a nissan leaf with 90mi range in southern california and only had to stop to charge outside the home a few times for days where I went between LA and Orange County. Otherwise I never really cut it close - and this was with the slowest wall outlet charging at home.

It's pretty perfect as a 2nd family car (and I may buy it for exactly that if the production model reviews are good) but yeah, it's a tough sell for a primary car with that range. Assuming they manage to meet their sales targets and stay in business, I bet it'll improve rapidly over the next couple of model years.

Exactly. 200mi EPA is essentially 130-150 highway in winter, which is stopping for charging every 2hrs going 65 - not feasible for anyone living in the midwest.
