So, what's the status of battle rigs after last patch?

So, the latest large patch introduced some fixes to rigs. I'm hesitant to give them a try right away, because the last and only time I've tried them, I ended up falling through the mesh few meters out of the gate, and I don't want to repeat that. What's the status of them now? Can I drive around the wasteland without fear? Or are there still times when they go through the mesh?
