Depends on the gas prices, but yeah, even in the US often 'fast chargers' would be equivalent or even more expensive than gas.

If you take fast chargers with the milage most EVs get (roughly 2mi/kwh), the per kwh price needs to be roughly $0.35/kwh or lower for electric to be cheaper (home rates essentially across the US are lower than this), but fast chargers often climb to $0.45-0.55/kwh.
