"If you really want to understand why an accident happens, you need to look at different things like the environment, vehicle, and humans together to understand this. I work to train police to investigate accidents. We almost have 67 factors to determine this, but we unfortunately look at only 5-6 factors," Dr Rohit Baluja, president the Institute of Road Traffic Education and director of Traffic Management College, said on the Rishabh Pant car crash.
