How many crossings without automatic gates are there, vs how many fatalities at those crossings, and how many people cross at those crossings at all? When you remember that other important things to spend money on also exist, the math probably works out for leaving many of the rarely used crossings as they are. In America, there are a few hundred thousand crossings and only a few hundred deaths. Most of those deaths are concentrated at a relatively small number of crossings, while most of the crossings have very infrequent traffic across them. It's the same kind of logic that has most train tracks not put behind fences. In populated areas where lots of people roam around, putting a fence up next to the track helps keep people off the track. But in most of the country, the population is too sparse and people being on the track too infrequent for anybody to rationally prioritize putting fence up alongside all the track. Half a billion dollars worth of fence to save maybe a few dozen lives just isn't going to fly when there are schools to fund, old lead water mains to replace, bridges to repair, NASA probes to Uranus, etc etc.
