Okay - let me piece this together based on everything you've said.
Vehicle - You said a "little" tougher than my van (Bod 16), but not a Roadmaster (Bod 18). No such RAW vehicle, so let's say Bod 17.
You also said it is a "small lorry", so I'll assume not an armored vehicle. Give it same armor as my van at 12.
Made up vehicle begs question of handling, but I think that will be academic, per below.
No Rigger template in RAW that I can find. There is Drone Rigger and Street Racer. Both have almost exactly the same pool for wheeled vehicles, with the edge going to Street Racer for the Gearhead quality. More of a "driver" type anyway.
But for the opposed driving test (limited by handling), you already said I got the ram, so we must cap his successes at 4 (which he can buy). Based on your wording: "You rammed him alright! Ouch!"- that double exclamation point really tempts me to give myself two net successes, but better be conservative when entrusted with rolling for my own enemies. Cap her at 4.
That means the attack is 17 (over the armor).
That's 29 dice for the vehicle's soak.
Soak for small lorry:
29d6t5 9So vehicle takes 8 damage.
Now the rigger (passengers - I guess not?).
His soak is 31 dice (bod + personal armor + vehicle armor).
soak for rigger:
31d6t5 8So he takes 9 physical damage from the attack (modified DV over his 16 personal armor).
Then the question of whether he was jumped in hot or cold.
I think we all know what we would choose...
So that is 4P to resist with Willpower (3) + Firewall (4 for his Compuforce Taskmaster).
biofeedback resist:
7d6t5 3So that is 1 more Physical, which fills his condition monitor of 10. Unconscious.
If she's got her autopilot on, she won't also crash.
So I've shown my work, tried to stick with all instructions given, and tried to be conservative.
This is because I am a bit self-conscious "GMing myself", so to speak.
There are also lots of other possible variables (including rules mistakes by me), assumptions you may not agree with, and I didn't know if you use Edge for the bad guys.
So there it is, but I will wait for you to sign off on in before I post a badass IC (I see Al hitting her head on just right so the Bulldog glances away but it stops he cold, sending her through the windscreen and thumping her head on my windscreen before I careen off to help the family).
So yeah, I'll wait for you to sign off before I post that....if it's not cool, let me know what is cool so I can get posting!
