While Dr Saleem, the Addl Commissioner, Traffic, has stated (check this) that he will be taking up an intensive drive against 'defective number plates' (the biggest issue here of course pertaining to the Kannada number plates - very few people want to identify it as such, since it is supposed to be a 'sensitive' matter), it will be good if citizens themselves start boycotting taxi's and auto's with number plates made out just in Kannada (or, not displaying the ones, made out in English letterings and Arabic numerals, as per the M V Act, prominently enough). Perhaps government agencies like BESCOM (see picture) could set an example, to begin with.
There is no trivialising the matter. Now, supposing BESCOM engages this vehicle to pick up an outstation visitor from the airport, and the driver misbehaves, how is the visitor going to be able to identify the vehicle to the police, if the most important identifying feature is incomprehensible to him? That is precisely what has been brought out with reference to this instance of an auto driver terrorising of a foreign professor's family. The matter gains further currency from this instance, where the police had difficulty tracing the vehicle involved in the murder of the the Gandhinagar corporator, because the number plates were made out in Kannada only.
Besides, this is a matter of national security. Now, what if a Riyaz Bhatkal (of Indian Mujahideen notoreity) chooses to perpetrate another act, like the attack on the KSCA stadium or the IISc? You may be dead sure he will engage a vehicle with registration plates in Kannada only, since the chances of its getting identified properly are less than 5%, with even half the police force unable to readily make out the letterings and numerals, which have no prescribed standards besides.
PS: This is not a Kannada vs English issue, nor a Kannadiga vs outsider issue. So, please don't bring these up in the debate here. Debates on those issues are on-going on PRAJA, and if you wish to contribute, you may access them here, apart from other blogs.
