This. The reason we hear so much about them is that they're so flashy - they appear rapidly, can cause pretty major destruction where they hit, and disappear rapidly.

You also don't get days of build-up like a hurricane, it's only around 10-15 minutes to go from "a storm that might make tornados (like many are)" to "one is likely to appear at X" to "hopefully you're already sheltered, it's here". Hunkering down has to be done rapidly, which is stressful and memorable, even if nothing happens to you.
