Why are terrorists choosing trucks as weapons?

In recent years, Europe has been terrorized by series of truck attacks mowing down pedestrians. And now the trend has reached the shores of the United States.
Uzbek-born Sayfullo Saipov killed eight and injured 12 in the Halloween terror attack in New York City on Tuesday, with a rented truck, a familiar weapon now favored by terrorists. Terror groups, particularly ISIL, have been encouraging their followers to adopt this tactic.
So why trucks?
Truck ramming has a high chance of success for the attack planners. It is difficult for authorities to predict and prevent. The method is also deceptively simple – it doesn't require an elaborate plot, nor does it cost much. All you need is a car, a crowd of people and a driver.

Is there any way of preventing these truck attacks from happening? 
Given the difficulty of protecting every public space with concrete barriers, those hoping to prevent these attacks need to prevent people from becoming radicalized in the first place, said Jason Burke, author of The New Threat From Islamic Militancy. 
“It comes down to what we know mitigates the terrorist threat: effective intervention, as far up the process of radicalization as is possible,” he told Newsweek earlier this year.
