There are two types of evolution. "Linear" and "sauteed".
Linear evolution is more predictable because it follows a line , whose steps are simply 1, 2 , 3 and so on.
In the case of sauteed evolution line is interrupted by factors , both positive and negative , to produce a disruptive evolution. But also they can produce "involution". Under these circunstances a market or industry prediction becomes more difficult.WWII created a linear disruption in both, positive and negative, because the war negatively affected many transport systems, but also helped develop and to perfect new technologies such as diesel engines and commercial jets, changimg completely the face of transportation.Desde entonces y hasta hoy la evolución fué muy lineal, y por cierto bastante estancadaToday there "5" strong concurrent factors, which combined can produce a new leap .A new evolutionary leap would impact strongly on both the economy and the activity of the transport sector.
The next jump is clearly visible. The question now is when and how it will affect us
This appears, right now, as neither lineal nor comprehensible; you might want to take the draft down until you've finished writing and translating? I get the basic drift about incremental change versus sudden leaps, but it isn't obvious. BTW, while English has words cognate to "saltar", the one you picked is strictly a culinary term; I believe that forked to "saltear" in Spanish. We talk of "saltation" in a stream bed, we describe something that's off-and-on as "desultory," but when we say "saute," the first thing that comes to mind is probably onions.
