Imagining myself in this scenario, in which case I would not be doing 155kph on a B road.
Opposing forces are:
-Probably speeding, it's not clear
-Passing on a solid
-Passing just before a rise, hence the solid line
-Passing... SIDE BY SIDE?!?!
I think this might have actually been enough to activate road rage for me. You know, assuming it went the same way and we didn't fuse our atoms together
