I don't think the biggest issue when facing something like this isn't that people didn't know it was coming for them, 99% of the time they do know, it is just they have no where safe to go.
Unfortunately that number is nowhere near 99%. In many households, if the television is not turned on, they do not receive the warning, and that can be a fairly large percentage of households in the path of any given storm. Sirens are one solution to this, but they are only really effective at warning people that are outdoors or very close to the siren sites, and it comes back to one of the points I was trying to make in my post: you should not trust some external force to alert you with no effort on your own part.
The sheer lack of underground shelters is a massive problem for Tornado Alley and there was no underground shelters available. You have two choices when faced with something like this, you either get under ground or try to get out of the path of the tornado which is also extremely risky and dangerous because tornados change directions new ones come down on top of you at any time and the roads do not necessarily go the direction needed to avoid them. We have to invest in underground shelters for the general population in these areas moreso than anything else or we are just causing these deaths to happen. Duck and cover does not save you when nothing above ground can withstand an f5. Most of what is built above ground does not even withstand much smaller tornados when it is a direct hit or it sits right on top of you for a prolonged period of time so I do not see the point of building anything above ground to be deemed as a shelter.
There is a pretty massive jump from buying a $30 weather radio to buying an underground shelter. While there needs to be a conversation about public shelters, that is a long term project over which any given individual has zero control. Conversely, there are things you can do to drastically improve your chances of surviving a tornado, and that's where I was trying to go with my previous post. Even in an EF-5, advanced planning and preparation can save your life.
There is an interesting relationship that many people aren't aware of: the stronger a tornado is, the easier it is to detect via Doppler RADAR. In Tornado Alley, this pushes warning lead times up high enough that running away from a powerful tornado is actually a very real and advisable option if you have no safe shelter. The unpredictability of a tornado's forward motion has been quite exaggerated, in part by the National Weather Service themselves over the last century. While the tornadoes themselves have a tendency to zig-zag, loop, and sometimes even stop in place briefly, they are still slave to the larger circulation within the parent thunderstorm. If you're able to interpret a map properly and can see which direction a powerful storm is coming from, you can absolutely have enough time to evacuate either out of the area entirely or to a nearby safe location, such as a neighbor with a basement, well ahead of the dangerous portion of a thunderstorm. However, in the vast majority of tornadoes, sheltering in place in an internal room of a permanent structure is extremely survivable, making that the best option on extremely short-notice warnings. Again, it comes in large part to how much information you have given yourself access to.
All that said, yes, there absolutely does need to be more underground shelters made available to people living (in particular) in central Oklahoma and Kansas, the two areas in which major tornadoes are the most common, as well as in the rest of the midwestern Tornado Alley and in the southeast USA's Dixie tornado alley (MS and AL, which also see significantly elevated numbers of major tornadoes).
