I'm not sure whether the intent was to hit cyclists with the car door or by hand. Surely the most likely to cause injury to the smacker would be to hit them personally - arm extended outside of the door would take the impact, while the door would be providing an ongoing force. Really badly expressed, perhaps someone could do better. I think it's more likely that the door was intended to take the hit, but the driver would surely have had an issue with damage in that case.

Anyway, even the slightest pat to a cyclist can result in injury - just falling off your bike can leave inches of skin on the road (major ouchie!) and depending on how you land, broken ribs and collar bones are not uncommon. I know from being friends/ related to cyclists.

However they were hoping to disrupt the cyclists' trips, it was still unacceptable and dangerous rather than amusing.
