The ratio has been way worse than that in my experience, especially in cold weather. Could easily turn a 3 hour trip from Seattle to Portland to 5-6 hours during winter, when mileage plummets on the freeway.

Obviously part of that is that the EV wasn't fully charged when we started, but that's the thing -- being low on gas for an ICE car barely affects travel at all.
