I was curious what the break-even is where the insurance discount covers the $99/mo FSD subscription. I got a Lemonade quote around $240/mo (12k mi/yr lease on a Model 3), so 50% off would save ~$120/mo - i.e. it would cover FSD and still leave ~$21/mo net. Or, "free FSD is you use it".
I believe, at the end of the day, insurance companies will be the ones driving FSD adoption. The media will sensationalize the outlier issues of FSD software, but insurance companies will set the incentives for humans to stop driving.
