Typical. Assuming the engineers that design these vehicles are too stupid to think of basic things like this.
True they don't always think of everything, but we're 20+ years into this kind of stuff now and the technology is pretty well refined. If you notice, the kinds of things that are missed now are real "corner cases" where several things have to be just right to make the problem occur.
These cars are instrumented to the gills and everything is interconnected. The computer is programmed to protect the car's systems. Not only can the car sense a no-start condition and stop cranking, it can usually tell you WHY. The systems expect certain things to meet certain criteria in certain amounts of time. If for example it expects to see fuel pressure within 5 seconds, and it doesn't, it will stop cranking after 5 seconds. If the engine is hydrolocked for whatever reason, it will sense an overload in the starter and stop cranking IMMEDIATELY.
A human is far more likely to keep cranking until the battery dies, the starter fries, or the engine is damaged, than the computer. How many times have you seen someone keep cranking an engine until something gives out? How many bent rods have been caused by people trying to crank through a hydrolock?

Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
