arabs/muslims think that the day of death as well of birth are fixed. so if you are destined to die, you will die no matter you use your seat belt or not.to them i would like to say that there is no place for suicide in islam. driving without a seat belt or doing any work without taking the required precaution is like attempting suicide.so my dear arabs/muslims take care of your life it is precious.
indians/south asians dont use seat belt because they dont know its use, rather the benefits of its use. by the way,seat belts are optional in cars which are sold in india.............i see it as a strategy to reduce population;)
