get your coords, get your camera angle, then with some formula calculate what cords you have to increase to teleport car right in front of you.
like ur cords is x 0 y 0. You need to teleport car 10 cords in front of you. If you are watching 0° (north, x) add 10 to x cord.
if you're watching 45° north-east (xy) then add 5 to x and 5 to y
i'm bad at english and very bad at math and scripting, but I hope i somehow helped you
