This is the sign on the back of many trucks and buses in Mumbai / Bombay.
They’re saying – ‘let me know if you’re there – I don’t want to bump into you any more than you want me to’.
Makes for a lot of noise- but, surprisingly few crashes (especially given the pot holes, animals etc on the streets).
Though I haven’t run the stats, I wouldn’t be surprised if IP Rights owners who ‘Honk’ about their rights also have less bumps and scrapes (in court).
[There are some exceptions to this, of course – usually when the IP Rights protect something of high value and other forces dramatically increase incentives to copy – such as Regulatory hurdles in pharmaceuticals.]
