I tried to drive in India on the highway after 15+ years living in the US. The highway was mostly empty, I was beginning to gain confidence and upped the speed (barely close to what I'm used to driving here). Out of nowhere, a truck came hurtling down in the opposite direction on the exact lane I was driving in. Had I not been alert, my entire family would have been decimated. Immediately handed the wheel back to my FIL.
