[Guilty Spark]

Sorry for bumping an old post, but the problem you all are describing here I ran into and found a fix for when I was making an adapted version of this hero for my clan's server - with the solid type set to SOLID_SLIDEBOX (3) and the move type set to MOVETYPE_PUSHSTEP (13), the car works normally. It looks like this already should be default, but this problem is directly linked to the solid type / move type.
