An Aussie local council got itself in hot water when it posited that one reason that local Asians got alot of tickets was due to the fact that the local signs were in English and the drivers couldn’t read them. Read about it here.
Of course the local Asian population was incensed and called the comment racist.
My feeling is that it was simply Political Correctness run amok. We have international road and parking signs — they are recognized everywhere and even where they are virtually unknown, like the US, they can be understood by anyone who can figure out how to drive a car.
I don’t expect to have English signs in China, and they have only very few. Likewise, the Chinese can’t expect to have Chinese Signs here, or in Sydney. Why is this so hard to understand.
