<div class="PlainText">I wouldn't say there is a trick, but you can check for this kind of thing using the built-in functions. In this case you want to check the car's "distance in front of" the road. If the value of this function is too great or too small,
then the car is past the side of the road, or off the road. Please see attached for a proof of concept.<br>
