There might not be lights but there's traffic, junctions, animals, road hazards..
What gear is that? If I was on aerobars and even just a London downhill I'd be doing 50kph without even pedaling.. in the country with some proper hills at 80kph.. I need brakes. Do you not have any bends in the road where you live?
It's a bikesnob build isn't it?
although the hills have to be considerable to allow gravity to take full effect.
