I am called 'Sir' When I am behind the wheel of my brother-in-law's Polo or my Senior's Octavia.
I am called 'Eda oove',
Malayalam for 'Hey you' or maybe its even more rude and degrading I might say, I dont really know an exact word for it and its considered disrespectful around here and they also refer to you as 'Mone' or 'Koche' which means 'Son' in English. It might sound cute, But I dont know how cute can it really be when someone much younger to yourself comes and calls you son.
(Well I'm getting sick of this 'Son' word so I have now grown a mustache! Lol)
And yes, when I'm in my Alto I really get discriminated, what makes me furious is that people, anyone and everyone thinks that you are someone who doesn't know to drive and that you still only possess a leaner's licence and so start hurling instructions when you are trying to park the car somewhere tight. Once these instructions from a stranger got so annoying that I asked him to step away from the side of my car, Cause I couldn't use the left wing rear view mirror. He was standing on the left side and irritating me like hell.
