In accident reconstructions, head on collisions where equal mass vehicles come to a stop on impact are virtually nonexistent. Physics says the much lighter vehicle should be carried backwards by the heavier one, but it never happens, the smaller car will go underneath or off to the side
Not sure. All I know is that there wouldn't be a tiny car for very long... ^_^
There is no false statement accompanying the question.
in case the speed they are traveling causes them to collide or rock against each other and scrape
You can be accelerating and traveling at a constant speed if you change directions.
Such an object is traveling at a constant speed in a straight line. Nothing will happen to it until the forces acting on it become unbalanced, or it runs into something.
When you (or an object) travel without changing speed, then you have constant velocity (speed). This means there is no change in speed (acceleration) when you (or an object) is traveling.

That doesn't make sense. What do you mean, what will happen? Happen to what..?
in case the speed they are traveling causes them to collide or rock against each other and scrape
Nothing
This depends on your speed and may depend on what country you live in. Where I live you should travel at a distance suitable for the speed you are traveling.
No such thing would happen. Matter cannot reach the speed of light, only massless things can (and they cannot travel at any other speed than the speed of light).
cruising speed
You can be accelerating and traveling at a constant speed if you change directions.
Yes. Because the truck is heavier.
Nobody knows for sure. We have never witnessed a physical object traveling faster than the speed of light.

Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
