Damnit. DRV fault on the remaining focbox. ???
first 0.5 km of the day. 
No idea if this is related to the first problem but continuing here because it’s suspect. board triggered a very similar feeling problem a cutout with the funny noise and then some drag. got home and found DRV fault on the secondary focbox.

I have zero clues at the moment what a DRV fault is and what causes it.
METR did not seem to pick up this fault though. I think it’s supposed to pick up faults from the secondary over CAN at this point. I think I’ve seen it do this. but it didn’t.
here’s the record from it happening.
