Sorry to hear about your crash. Gravel can be a real pain for sure, no pun intended. I can't believe I'm saying this but gravel and twigs concern me more than motorists. I feel like I do a really good job of watching the behavior of motorists, but random stuff in the street (like the busted car windshield that hasn't been cleaned up for 2 weeks on this main road) really concern me.
Good luck with recovery!
