la surface vibre constamment

[LanD]

have you ever encountered this problem: the steering wheel vibrates constantly yet I have correctly named my roads in ROAD1 ROAD2 ROAD 3 and my cubes AC_PIT_0 AC_START_0 the Y is at the top and the z points forward why I have so many bug yet I seem to follow these looping tutorials to the letter, there's a mistake somewhere

ROAD1, ROAD2, ROAD3 are not correct. Should be 1ROAD, 2ROAD, 3ROAD
