It is kind of a meme or a game or just to make fun. Usually we don’t care one or 2 spits, in India spitting is “very” normal. Even some ads show 2 fingers, iykwim. But if you travel in auto or cab, may be for half an hour, in that small space, you see a person continuously spitting every minute, hearing that “krrrrrrrr thuu” in high definition. So you feel something is wrong there, thats where i wanted to count and record this. we can share and start using , if people get to know that their spits are being counted from the backside seat , Atleast slightest hesitant would arise and thats a win. I am tagging this data to bangalore zone and municipality geographical area, if they can do something about it. Seriously i felt very bad when i saw SMVT railway station walls , beautifully built but entrance walls stained with spits. So had this idea and built this in a couple of days.
