what angle range prevents a crash?

[alan2here]

Take a 2D enviroment that contains a straight line where the x and y coordanates of the two ends of the line are known and also the position of a car and the angle it is facing (7 values).

 

The car moves forward in a straight line. Is there a simple, reasonably computationally fast way to work out if the car ever intersects (crashes into) the line?

 

Would it become much more complicated if one of thease additional pieces of information was needed? either where did the intersection occur or given multiple lines which one was intersected first.

You will be looking at sinusodial functions then to calculate angles in the form of radians.

yes. I imagined that would be the case.
