Insurance is highly variable so it’s not true that “EVs cost more”.
I have identical full coverage through Farmers in Milwaukee area on:
2016 Chevy Cruze Limited: MSRP $22k (who didn’t lease of these in Dec 2015 amirite?!)
2014 BMW i3 REx fully loaded: MSRP $55k
My i3 coverage is $44/mo and the Cruze is $65/mo. 
Does this make logical sense based solely on MSRP? Heck no it doesn’t, but that’s insurance for you!
