I saw this a few weeks ago, and have been meaning to share it. Unusual!
The roads here are too dangerous for cyclists of any description – you can tell by the daily death toll of bicyclists and motorcyclists (whereas car, truck, and van wrecks/injuries/deaths are quite rare) – which is why I never bicycled before I got a car, even though it’d have been a huge help in my daily life around town, since it’s so much faster and lower-impact than walking. (You’re not supposed to bicycle on the sidewalk, which is sometimes stupid and sometimes sensible, but they have to make blanket laws for all situations instead of assuming anyone has any brain anymore.) But for the suicyclists who’re going to do it anyway, I did notice that cars were tending to give this tricycle more space than they give bicycles when passing, despite it not really being that much wider than the person.
