> Among this group, those leaving between 6:00 a.m. and 6:29 a.m. reported the longest average travel time to work at 32.8 minutes.

So, if "30 minutes" was actually how you measured range (and not in miles), the average worker in the longest group would burn fuel for 3 minutes, instead of 33 minutes. This is 90% less fuel than a traditional hybrid car would use in the same time.

Travel time != travel distance. When you're stuck in traffic, an electric or hybrid car will not consume any energy except for fans/heating/AC. An ICE-only car will have to keep its engine running.
