For us, the primary motivation was a better drive. EVs are just a better technology and the future and far better than having gears and narrow power bands and clutches (whether manual or automatic).
Saving money wasn't on the radar since we would be buying a brand new car and hence losing a lot more in depreciation than we'd ever save in fuel. Not visiting the garage to fill up has been nice.
The environment didn't feature on the list. I still think running an old ICE car into the ground wins here.
