The car works without landcontact LOD. Its not needed, but youre in for a bumoy ride. I got now v1.91 ofp and i testet the start-model, its got just 0.000 and geo-lod and nothing more and im able to compile it and drive around, and i dont get any crashes to desktop or anything, tried both using Cilvilian->Car->My First Car and Empty->Car->My first car
But its hard to get into the empty car due to the fact that we havent made a "pos driver/cargo" vertex in Memory LOD. And i assume that these start locations are at the model origo by default when nothing is specified, so if you want to get into the empty start-model, you must run into it (the geo isnt very good, it seems) and get to the center of the car, then the Get in action will appear.
Hope this clear things up a bit.
