The only way to overcome range anxiety and have just one car is a plug in hybrid.
My 2013 Chevy Volt is the best car I’ve every owned so why do I need a Model 3? I’ll answer that question: the Model 3 is a force of nature with the connectivity, brains, battery-only range, and charging infrastructure that my Chevy can’t offer. But that doesn’t change the fact that the original Volt was a stroke of GM genius (hat tip to former GM executive Bob Lutz*) and the fact that it was an early EV pioneer (released December 2010). And the fact that it’s still a relevant, highly-practical EV.
