People don't buy cars by thinking of the crash safety factor while buying the car. So crash safety factor is not at all taken into consideration, if it is taken then the consumer won't buy any car or vehicle. Crash damages occur mainly because of the attitude and behaviour of the driver, if we drive the vehicle in a correct speed (speed limits mentioned in sign boards) then we are safe to an extent but then all persons may not drive in a correct manner some may be rash too so we should also manage/correct their wrong driving sense to stay safe so its immaterial to which car you drive.
For example: In a bumper to bumper traffic people jump into your lane so we just let them into our lane by just braking. So by these ways the crash can be avoided and damages can be controlled. So even in highways too when one vehicle overtakes in a rash manner then we must give way to avoid accidents which many people doesn't do it properly.
What you said is true for Indian buyers, that too lower segment (say under 5 Lac car) buyers and in some cases, extreme high segment (say above 1 Cr car) also where performance is more important. The big population in between, i.e. 5 Lac to 1 Cr rupee car buyer, certainly takes safety aspect into consideration.
Since this thread and topic is pertaining to supercars/exotic cars only, I would not generalise any statement. This segment of car buyers look into other aspects because they already expect a certain degree of safety from their cars. It is not that they do not consider this aspect at all, but most (in fact all) cars of that segment are much more superior in passenger safety.
I didn't mean that supercars can immune the driver totally, but they are certainly safer as compared to other general non-supercars.
After all, a driver is responsible for his safety and not the car.
