That is dumb. Go to a developing country and see what happens when everyone is aggressive. Everyone cuts off everyone else and drivers brake a lot (none of this waiting for a gap before entering from a side street, for example, the understanding is they'll brake for you). The end result is much more slower traffic.
I think that's kind of their point; if no one else is being aggressive, than being in the one car driven aggressively might be viewed as an advantage. A more civic mindset might prefer a driver doesn't try to take advantage of this because of how it might affect others and a pragmatist might be concerned with the potential to influence others to do the same and ruin the status quo, but I think empirically there are a sizeable number of people who would view it as an opportunity rather than something to avoid .
