CNG run vehicles

Sohel Ahmed, Dhanmondi, Dhaka
This may sound funny, insane to many, but I suggest the government ban CNG driven vehicles as the government is so concerned about security and terrorism. Funny but it is true that when a car enters a hotel, hospital or the secretariat, one will notice that a group of people in uniforms will ask you to open the trunk of the car and will certainly look under the car for some sort of explosives or guns/ammunition, I don't know what else. These so-called checks not only delay the entry but also help the congested traffic to clog up at the back. By searching the trunk and the bottom of the car what have they found so far is a question to me and to many others who often face this unnecessary so-called security checks. The security personnel don't bother to look inside the car or the bags kept in the trunk or the seats which are the most likely place of carrying explosives. Also, they never ever check the front where the engine is located. They will check and let you go like the sunrise and the sunset factor. If someone wants to blow it up, it does not take a nuke scientist to carry out such an attack. The gas (CNG) cylinder which 95% of the cars and busses have are good enough as in reality they are the mobile bomb which was legalized by the governments of the past and the present. We have already seen many times what the CNG cylinder explosion can do and if it explodes in a parking lot with 20-30 cars parked, I think it is strong enough to blow up a 6 storied residential building without too much of a hassle. So my question to the authorities concerned is (1). Are we really vulnerable to terrorism or (2) Did you ever think of the CNG factor? If the 1st point is valid then I think all the CNG vehicles should be banned or the cylinders should be taken out so that the terrorists do not get the opportunity to play the devil's role. This will also help reduce the traffic congestion in the city. As fewer people will use cars for short distance to save petrol.
