If it's a down slope or even a flat grade when the road's in good condition, maintaining the speed isn't that difficult for an experienced cyclist on a decent road bike. My experience has been that many drives in the US at least get downright angry when they see cyclists, honking at you and even occasionally running you off the road. And that's when they notice you. Even on roads with dedicated bike lanes, I've been run off the road both by people who've noticed me and by those who didn't when they drift into the bike lane.
