I think having a long range explosives laden drone hit that sports stadium is way more scary. And more likely to come to an urban center as urban terrorism. Unfortunately. My 2c.
(And only fairly recently have we really seen anyone use cars for terror attacks. And they are still fairly rare, considering how ubiquitous cars are.)

I think many people misunderstand the degree to which society is contingent on the good faith participation of most people.
It is like a prisoners dilemma where we have managed to convince 99.9% of people to cooperate and the whole thing can easily fall apart if they dont.
That should give people who want to impose their will on others more pause than it does.
Sure, but if you are willing to give your life 'to the cause', cars work.
In reality there are hundreds of other ways someone could devise attacks like these, technology doesn’t really matter that much.
