You've assumed the road is wide enough for byway traffic. Around here they are 30 feet wide, including at the crest. >As a driver, I would hate to crest a hill on a country road and have a cyclist coming straight at me. I’d have to swerve into oncoming traffic to avoid him. That’s bad. This occurs on both sides of the crest. You can only hope for a near miss. >As a cyclist, I would hate to crest a hill on a country road and have a car coming straight at me. Because if it doesn’t swerve, we run into each other head-on. That's up to you. You can choose jump as a last resort. Getting hit from behind, you're unaware of everything until you're launched into the sky.
