The driver would have collided with the steering too before reaching the glass. It could be a case of head injury for passenger while driver would have suffered head and chest/abdomen injuries.

The punto has taken the hit very well. The cabin is intact and the crumple zone has absorbed the impact rather than jolting the passengers.

The safari did exactly the opposite it seems to have transferred all the kinetic energy to the frame and occupants. I wonder how much of that can be blamed on the bull bar.

^^ I think it must be squarely blamed on the bull bar which must be bolted to the chassis. So it protected the car body and passed on the shock to the occupants.

I'm not sure I understand the argument about the bull bar. Even in Safari, the cabin looks intact. A-pillar is in perfect shape. Windshield is broken since the passengers didn't wear the seat belts and got thrown forward, which is the precise purpose for seat belts in a car. Where does the bull bar come into all this?

Entire blame for injuries should go to the passengers who choose not to wear seat belts!

EDIT: If the passengers in Punto escaped unhurt even without wearing seat belts, I've just two words for it - DUMB LUCK :)

Just spotted an accident between a lorry and a car on the flyover that connects the GST road near Chromepet(A2B and Buhari) to the Pallavaram-Throaipakkam road. Couldn't identify the car, but it was being pulled out using a crane. Not sure of the details, but the roundabout is blocked completely and those who take the flyover to turn towards Pallavaram are asked to go towards Chromepet and take a U turn in the GST road. Seems like it happened around 9-9:15.

Yes, even the Safari is intact, but the Punto is a hatchback while the Safari is an SUV.

I have mentioned minor injuries, I guess you missed that part. One guy was with coolers and had some injuries near the eye. Punto's windshield is intact because, the passengers are seated lower, when compared to the Safari. No one had head injuries like the people in the Safari had.

The Punto is one solid safe car, no doubt, reminds me of another incident on the ECR, where a Punto collided with a Xylo, the Xylo was in shambles while the Punto had a damaged right fender and headlamps. :)

I saw the lorry lying on its side at 8 AM. Couldn't spot a car around it though. There was a fire tender and a lot of police men.

Agree completely with the seat-belts part of your post.

About the bull-bar, if it's bolted to a vehicle's chassis, the force of impact bypasses the crumple zones (the intended recipient of the force) and passes onto the chassis & cabin through the add-on contraption (which it wouldn't if the bull-bar didn't exist).

A lot of people install bull-bars to protect their cars from getting damaged, but what they forget (or don't know or care about) is the car is designed to bear the brunt of an accident and take damage so the passenger(s) don't have to.

No. Objects travelling at so many kmph are going to have the same amount of potential energy whatever vehicle they are in

Exactly. Seat belts is the vital issue here.

Just look at the bus full of passengers going so close to the burning Indigo! When will Indians have common sense? The fuel tank (petrol I believe) or even LPG/CNG could have exploded at anytime.

Amazing!

I'm fully aware of how harmful a bull-bar can prove to be and I'd never recommend it to anyone but that's not the point here! All this theory about how bull-bars misdirects the force of impact is relevant only in case of damage to passenger cabin area.

What I don't understand is how it becomes relevant in the context of this Safari-Punto accident where the cabin area of both cars are intact.

EDIT: To rephrase the point I'm still not clear, how would the absence of bull-bar in that Safari prevent the injury to those passengers? I'm speaking about this specific instance and not a general case since someone mentioned that the entire fault is with the bull-bar.

There is a curve on a main road, followed by a steep descent, followed by a near dead end and and a left turn. What happens when a bus takes this curve at a high speed, fails to brake in the descent?

The bus that caused this damage:

This is the second time the compound wall and the kitchen wall of the house was demolished by a speeding bus and truck coming down the slope and losing control, hence ramming straight into the wall. Thank god no vehicle, or any pedestrain come in the way of the bus.

:Frustrati

Feel sad for the house owners, and moreover what a shock for people inside the house, to expect a truck or bus appear out of a wall. And this, for the second time after a gap of a year or so.

Someone well-versed in Physics might explain better (or correct if I got this wrong:)), but let me try.

Isn't the primary function of crumple zones to absorb the forces of impact and 'soften' (there might be a more accurate technical term for this) the impact on the passenger cabin as much as possible?

Agree with you completely that the absence of seat-belts (and not the presence of the bull-bar) is responsible for the injuries. But it's possible that if there was no bull-bar, the crumple zones would've absorbed more of the impact, and the occupants may have been catapulted into the windscreen with slightly less force. Still mighty stupid not to belt-up, but the bull-bar probably made things worse. They would still be injured, but probably a bit less grievously.

Also, not all structural damage is visible immediately. How the chassis/body was affected under the impact forces may be unknown (no visible damage but reduced material integrity due to absorbing impact forces), and may cause issues at a later date/incident.

Not having bull-bar could have resulted in to the occupants being thrown at the windshield with less force which means less injuries. What bull-bar did is it transferred all the forces (kinetic) directly to the vehicle chassis (and eventually to the occupants) as it is not designed to crumble unlike the car body parts.

If they would have belted then the bull-bar effect would have resulted in to a bigger jerk which could result in to neck or spinal injury.

Look it at it this way: having bull-bar is liking sudden braking and not having is like gradual braking. You know which will hurt more especially without seat belts.

I believe you are referring to Punto-Safari in the accident... it is a body on ladder frame chassis, quite different from monocoques. The latter are more forgiving in accident, which is why the Punto's passenger shell is seemingly intact, but the body on ladder frame chassis (typically old SUVs with full LSD & their variants) are not that forgiving (based on an old study in US).

No doubt the Safari passengers paid price of not wearing seat belts as well :Frustrati.
