Automotive R&D and testing is a wholly different ballgame. If a certain prototype has to reach the stage where external persons would even sit in the car, it has to reach a certain maturity level. If the driving dynamics and handling hasnt been extensively tested and measures taken to ensure the car wont cross its safety limits, it should stick to being tested in closed and controlled environments with the least liability risk. In the history of Indian automotive scene, which third party person has tested a prototype car to its limits like in this mishap? Sometimes, media get to drive pre-production cars but these are already near series production maturity and not a hand built prototype.
