According to a media report some fraudsters made some quick money purchasing Two-wheeler insurance purchased for four and six-wheelers through Tata AIG and policybazar
Since most vehicle owners do not file insurance claims, this was noticed initially.
Only during an audit, it was found that the two-wheeler insurance was purchased for vehicles whose registration number correspondended to cars and six wheelers.
The vehicle owners probably thought they were getting a very good deal, and the fraudsters made some quick money, since the car insurance is far higher than scooter or motorcycle insurance

So it appears that following the government policy of falsely claiming that school dropouts are engineers to maximize their BRIBES, insurance fraudsters purchase two wheeler insurance for cars
