Getting crumpled so much by just hitting an under run-bar of a small size tempo is something really concerning. Though the speed of the vehicle isn't known in the video but by the looks of the traffic on road, must be around 50-60 km/h and assuming that, the damage caused is extensive. 36% high tensile steel used, Hartec platform is said to be quite rigid but in reality the facts seem to differ. I remember that Ciaz Vs i10 accident, in that too, CIAZ's front crumpled quite a lot and it was said the crumple zones did their job and all but frankly, the concern is very much there with regards to MSIL car's capability to withstand the impact. I have myself seen Celerio Vs Cycle Rickshaw and that time Celerio too got extensively damaged. From a purchaser's view point, I would say, there are options like AMEO Diesel, Ford Aspire & Tigor which give confidence of a better build quality in comparison to the Dzire. Let us not solely depend on the provision of ABS, EBD, Airbags etc rather we should be considering the quality of build as well when making a purchase decision. We live only once hence a compromise on FE is far better than compromise on the safety of life.
Though a Off-Topic Example but I'll share here, We all construct our homes and we fix all types of safety & security gadgets in it but if we compromise on the structure of the house itself by not using good quality iron & steel and other requisites, then the structure is bound to be flimsy and won't withstand test of time and no amount of safety gadgets can make it better. Hence, it is equally important to have a strong structure to complement the top notch safety devices.
