I had a few suicidal NPCs do that to me but fortunately managed to avoid hitting them all, very annoying though, how they're able to drop out almost on top of you/the station.
I'm running "D" rated on mine, albeit with Dirty Drive 3, to save weight - needed the maximum jump range for this CG but might have to look into fitting "A" rated, if they help out that much. To be honest, even if they don't, getting more than 150m/s out of the truck would be nice
Edit: Then again, the T-9 is a huge barge, its not meant to feel like a sports car, so I might just leave it as is, since it feels right, even if its a pain in the backside
