There needs to be police who will start to come out and shoot you if you take too long to blow yourself up.
You need to also enlarge the area, and also add bus stops and pizza parlors, but of course, those areas would be more heavily gaurded by police... some even undercover... you would have to quickly look for some kind of identifying information that would tip you of that they were undercover - this would definatly make things more real, and add to the "tension" of the game.
I agree with the idea that there should be bombers with different capabilities, like car bombers, fast runners, women, fools who will get nervous and blow themselves up within 10 seconds, etc.... oh, and the women bombers should flash their tits just before they blow themselves up... you could even have tits rolling around on the ground, like the heads... oh, and while you are at it, the women walking on the street should be given BIGGER TITS... all the women in Isreal have BIG TITS... yes, yes - and they have nude sunbathing there too... the bomber could go down to the beach and check out all the chick's asses before he takes himself out... oh, and don't forget to add a bunch of Russian prostitutes, the streets in Tel-Aviv are loaded with RUSSIAN PROSTITUTES.
