Yep,and as an engineer that's hard to imagine people that don't think of the efficiency as a primary feature.

Efficiency misses the point, it's convenience: a 3 minute fill-up instead of a 60m fill-up.

Since you mention a different point, let’s look at that.

When you charge at home filling up takes 6 seconds: 3 to plug in, and 3 to disconnect. Sure in between these two 3-second periods you have dinner and sleep, but you were going to do that anyway. It’s not taking any extra time. This is the normal case for most owners day to day.

Putting your priority of convenience first, I would take 6 seconds versus 3 minutes any day. So electric beats hydrogen by a factor of 30 on the metric you regard as more important.

Convenience is being able to use a ubiquitous existing fuel distribution infrastructure, rather than traveling to one of a tiny number of stations. If your response is “well, that won’t matter once hydrogen fueling stations become common”, then you’ve identified the problem.
