40% might be on the low end, riding on a motorcycle you can look right into people's cars and so fucking many are just staring at their phone in their laps
I used to ride all over the place on a bicycle on dangerous roads even with drivers mostly paying attention, now I wouldn't dream of sharing road space with cars on a bicycle. At least a motorcycle can move with traffic and get away from dangerous drivers, you're just fully at their mercy on a bicycle at 18mph.
