Well, here I am again, with the follow up of the fisrt one...
This incident occoured about four and a half years ago. This is why I had to get my engine replaced.
The Cars:
Honda City 1.5 EXi driven by: My dad.
Opel Astra(with a TC!!!) driven by: My Cousin.
Stretch: Mysore Road Highway(Which NH is it, btw??!)
We were all coming back to B'lore after a really nice trip to Mangalore, and we decided to stop at Mysore for a while. By the time we got back on the road, it had become evening, and we were pressed for time - dad had an important meeting - so we decided to take thee roads a bit quick. In no time we were out of Mysore, and were heading back owards Bangalore in formation (Honda then Astra), cruising at about 120km/h on a ssparsely populated stretch of road. There were a few other vehicles doing roughly 100-110 km/h there as well, so it was a very leisurely sort of drive. Soon it becomes night, but we keep going at pretty much the same speed, slowing down only when there's a curve or a road sign.
We're doing 110 now, and everything looks great, when alll of a sudden this Sonata that we're just behind brakes and takes a REALLY SHARP QUICK LEFT. Dad swerves wildly to the right, then back on the right side of the road. Before we could even recover from that incident out of nowhere we see tons of smoke, and a fire on the sidee of the road.
We slow down, because there's mild visibility(30-35m) and we can just see a truck thats broken down. Theres absolutely no oncoming traffic, so we gain speed again - from about 80 to 100 - and prepare to pass the truck.
Just as we reach the truck, we suddenly see that the driver has kept stones marking the truck - BANG IN THE MIDDLE OF THE ROAD. And these aren't small ones iether - they're like uncut ROCKS that come upto half the wheel height. Without any time to do anything, dad slams hard on the brakes, forcing the tyres to slip, and we run straight over the rocks. I',m sitting in the passengers seat, and I feel the rock denting the undercarraige after a horrific sound - like someone using a jagged blade to slice through steel. The whole car shakes, and the engine doessn't stall or stop, it just dies. Behing the scene is no better - my cousin brakes hard too (and he's got Brembos, but pathetic suspention), so the whole car starts to lean forward. In the rearview mirror, I literally see the impact and his tyres jump up out of contact.
Finally, both cars come to a standstill (one way or another) and we all get out. First everyone from my car gets out, and then we all go to his car. First thing he does is he opens the door, and hands me the gear lever - THE ENTIRE GEAR LEVER BROKE AS HE WAS ENGINE BRAKING WHEN IT HIT THE ENGINE. Luckily no one is hurt. Suddenly the truck driver comes out, and he gets screamed at by dad and my cousin. The guy lit a fire, and blew all the smoke onto the road sso we could see nothing! On furthur inspectio, the Astra's enine had come loose, and was now hanging at an odd angle. I removed the mats from my car, and I could see a long line where the rockss had pushd the undercarraige up, just in between where my legs had been a few seconds ago. Phew. We opened my bonnet, adn the engine looked fine, apart from tons of smoke. We looked under the car, and got a huge shock. There was a clean cut right doun the engine - amd when I mean cut, I mean the engine had been SLICED OPEN by the rocks. That pretty much explained the sudden death of the engine.
Luckily Insurance covered ALL of it, except 10K, but heck, with total repairs hitting 6-odd Lakh, we didn't mind!! It mainly went towards buying a new engine, as this one had been totaled.
Scary incident, and luckily no one got hurt too bad. My cousin got a cut on his hand from the lever poppng out, but that was all. I love my Honda - the cabin stayed enclosed, albeit a bit re-shaped

!!
I have learnt to never trust any Indian road like that again - not much light, and no one around - thats when I get extra cautious.
