We all know people here tend to drive in the right lane on the highway despite being illegal and the police do giving fines for it (as some older angry posts here can attest to).
Despite being a legal signal (flashing to indicate intention to overtake), too long or persistent flashing can be considered aggressive driving under the new(-ish) laws passed in 2020 to deal with the road rage incidents.
But some drivers are just completely oblivious to it! I know most are just too old or distracted to even realize someone is flashing their lights behind them, but I noticed some regional differences that make me think a lot of people may not know the meaning of the signal.
In special, I hardly ever see someone with Kansai* plates miss the signal, but in Kanto it goes completely ignored by everyone except professional drivers (trucks, company cars, etc). The same trend appears to form between countryside and large cities (countryside plates get it, big cities plates don't).
Is it is that people in some areas don't know what that signal mean?
