Well, enough of this stupid debate! I dont want to argue on silly matters! Everyone have their liberty to choose what they want, but I suggest them to choose what they want after reviewing thoroughly and know the limits of their car! Drive safe! Be safe!
Nobody is arguing that the ertiga doesn't have bad suspension/handling. It is a given. However, everybody buys a car as per their requirements and budget.
As long as you are happy with the ertiga, everybody is as well. What I can only do is request you not to assume things. Accidents happen due to a lot of factors. You say that the ertiga's handling and suspension will ensure that one may be able to avoid an accident (or whatever else), you still can never be sure. Even the german saloons which boast of high safety features will never guarantee that you will come out alive post accident.
I can also put forth another perspective: Ertiga's good handling will tempt me to drive at high speeds on the highways (even though it is unsafe). Xylo's boat like handling (which is anyways over-hyped) will ensure that I will never drive fast in the first place, hence 'theoretically' reducing the chances of an accident or my survival chances if one were to occur. It's just a perspective. Don't take it in a literal sense.
Every car has it's pro's and con's. You buy it if you want to. Just don't make assumptions. That's all.
Thanks,

P.S.: this is from a person who actually likes the ertiga, but wouldn't buy one. I prefer the xylo/quanto due to my priorities.
