There’s this idea I’ve been considering for a long time.
Imagine putting a remote controlled firework smoke bomb under the tailpipe, hidden from sight. At best a really stinky one that smells like burned rubber or something.
When someone follows to closely, just fake an engine issue or something by activating the smoke bomb and fill their AC air intake with the smell of burned rubber for weeks. Just to teach them to not follow too closely again.
90% of the things that Japan introduced according to comment sections on the internet never happened (or never made it past the prototype stage) and the rest was actually introduced in Korea, not in Japan.
The Japanophilia is strong with a lot of people on the internet.
