^^no, not that sarcastic... just a little bit.
if epic looks for a fully scripted cod-like scene... yes, possible, but loads of work in scripting, modelling and trying to always beat out the crappy physics.
if simply enter another nonstatic that follows waypoints when triggered > depends on the right model to "catch" the player in addition with some scripts to lock WASD and move the car. with v119 there is even more than 1 way to do it. you may bind the entity to the player and use plrmove/force whatever and script playermovement while the car.entity is bound to it. you can also use a propper model (as said a buggy without top but with roll cage seems best) and simply let fpsc physics catch the player, but thats a risky one because of the crappy physics (especially when "driving" on an uneven ground). i havent checked, maybe the player bounces on the nonstatic (also because of crappy physics), you have to test.
try a usefull entity and use people/follow and jump on it, maybe it works, then you just have to use the right model (caged).
the old fashioned way is a fakehud/model to "enter" the vehicle and drive, as you can see on the old chopper out of the tgc-store.
nowadays you can attach a model instead of only a hud.
you see there are different ways to handle this, but maybe you have to accept that it wont look, function and mainly feel as what you have in mind.
