Setting path for AI to drive?

Hey, i am trying to recreate an accident and i need the 2 vehicles to go a certain speed and hit at a certain place... and it is extremely difficult having to set the cruise control for both and then turning CC on then tab to the other vehicle and turn CC on.

I've seen BeamNG realistic crashes videos and they have the AI like passing vehicles and doing certain things... how could i do that? I seen that there is a waypoint mod which would fix my problem but it is outdated.... any ideas?

 

Try doing it using slow motion, if its only 2 cars it shouldn't be very hard.
