The biggest barrier for me is real-world battery replacement life.

My daily driver is a Subaru with a shade under 300,000 miles, my son's daily driver is a 2000 model-year. So obviously I like to run my vehicles a long time. Doing my part to keep my carbon footprint low.

I know what happens to the Lithium Ion batteries in personal electronics after the charging cycles start to add up. The capacity gets lower and lower until they are virtually unusable. I'm waiting to see how long/how many miles the car batteries really last before they need to be replaced. On some models the cost of battery replacement could be much more than the car is worth--and won't be a DIY job... Buying a new electric car every 8 years because its battery is worn out is not my idea of sustainability
