Surely the answer there depends on what's in the intersection - whether you want to roll into it or not. The answer may well be c) gun it and hope for the best

Surely the answer there depends on what's in the intersection - whether you want to roll into it or not. The answer may well be c) gun it and hope for the best! WRT the two cars crashing - I would bear in mind that immovable objects are quite uncommon, most highway barriers are compressible. So whilst you might be strictly correct I'd imagine few people crash into completely stationary objects like bridge supports without crash buffers.
