Glitches on default (Estoril '88) map

[Racecar56]

I went through one of the red trucks on those itty bitty roads.
I found out because one of my turns made my car go nuts, and for that reason, found that glitch. I'll svn up right now.

EDIT: OK, the trucks are colliding now, but the ground is still not colliding. Here is a very easy way to reproduce the bug.
I'm using development version, you should too.
Go to the Estoril '88 map. Go forward quite a bit until you reach the big sign. Turn left to that little road, go down it a bit until you notice a 'parking lot' like area with a campari sign. Go there, then drive CAREFULLY down that road. To the right, you will see brown ground. Just drive into it... and you will fall into the never-ending abyss of death. Drive forward, and you will run into a red truck, where-as in the previous SVN and stable versions, you'd go straight through. hock: [/i]
