Not sure how that makes sense, it takes a third of the time, but you're only going 5 km/h faster?

I presume they're beating some ill-timed traffic lights and overstating the savings.

Yes about traffic lights pattern: 5 traffic lights along the way, each with ~90s wait time or only a zero or a single wait and then riding the "green wave". So not overstating the savings either.
