There are plenty of cases where cars are not faster. For example, if I want to buy some milk or a newspaper, it is much faster to walk to my local shop than it would be to get out my car, drive there, find somewhere to park, etc; if I want to visit another city, it can be a lot faster to cycle to the station and take a train. And if I want to visit another continent, my car is totally useless!
In short, the car is only the fastest solution for a certain type of journey (a distance of between maybe 2 and 100 miles, or to a destination that is not well served by public transport). In the same way, an IDE is only obviously superior to a general-purpose text editor like vi or emacs for a certain type of programming project.
For enterprise architecture in Java, an IDE has big advantages. But for short programs that glue a couple of CPAN modules together for a one-off task? It's probably quicker to walk.
