The suitcase bomb was compared to the ridiculous pressure cooker bombs used in Boston, not car bombs. I did not state that they'd be worse than a big car bomb. I did not make any such comparison.

You misunderstand my argument. I'm not saying that there's very little terrorism, therefore security is a waste of time. I'm saying that many of our security measures are a waste of time because they don't stop terrorism, and I say this because they're trivial to bypass. That terrorism is so rare in this country is not because of agencies like TSA, but because there are approximately no terrorists to be stopped in the first place.

In places where there are a lot of terrorists, they carry out bombings pretty regularly. Regardless of whether you think it's effective, they clearly do. Yet they don't do it in the US. And it's not because TSA is stopping them, nor is anybody else set up to stop those sorts of attacks that regularly happen in places like Iraq. The only reasonable conclusion is that they don't happen because nobody here wants to carry them out.
