Vehicle-ramming attacks are considered unsophisticated, in that a perpetrator could carry out such an attack with minimal planning and training. It is likely that terrorist groups will continue to encourage aspiring attackers to employ unsophisticated tactics such as vehicle-ramming, since these types of attacks minimize the potential for premature detection and could inflict mass fatalities if successful. Furthermore, events that draw large groups of people—and thus present an attractive vehicle ramming target—are usually scheduled and announced in advance, which greatly facilitates attack planning and training activities.
