Is it really that painful? If you are charging from home, you just look at your local power rates. If you charge for one or two road trips a year, you don't even bother calculating that. If you don't have charging at home, then you add the charging costs of the superchargers you usually go to, actually I'd be surprised if your vehicle couldn't just tell you those numbers.
It makes sense in Hawaii, CA, and NY compared to local petrol prices. Heck, UK, France...it doesn't make sense in countries that heavily subsidize gasoline, like Iran, Saudi Arabia, and maybe Venazuala.
Chinese gas prices being what they are, and electricity prices being fairly low, you don't even need to really bother doing the math. The bigger cost is going to be parking and plate costs.
