I never actually stated VISA requirements because there isn't. I merely said about my situation. The IDP is actually valid for a year, however can only be used for 90 days during a visit. Go and check with DLT or local police.
If you are convinced that there's no requirement that's upto you. However, becareful because if you have an accident and require to use your insurance, the insurance company may refuse you're claim if you don't have have correct licenses etc. Google Roojai insurance and check with them.
