How much damage can a sociopath do with a 7kg bike with no airbags?

  1) 7kg is on the featherweight end of the bike scale - that is not representative of most bikes on the road 2) A fair bit when you include the 80kg rider going at 24kph into an unaware pedestrian.

    Are we actually going to compare the momentum of a bike in a vacuum? I will give you 20kg for a bike even, because the weight of the bike is so negligible. 100kg * 24km/h = 2400 kgkm/h vs a car If we cross-reference this with a list of pedestrian fatalities based on speed [1] Assuming a standard car size of 1000kg. 1000kg * 25kph = 25000 kgkm/h == 10% Risk of severe Injury 1000kg * 37kph = 37000 kgkm/h == 10% Fatality 1000kg * 51kph = 52000 kgkm/h == 25% Fatality 1000kg * 67kph = 67000 kgkm/h == 50% Fatality 1000kg * 80kph = 80000 kgkm/h == 75% Fatality 1000kg * 93kph = 93000 kgkm/h == 90% Fatality I'm not saying this doesn't happen, but you're looking at momentums that are an order of magnitude smaller than momentums where people are at severe risk of injury with a car. I will choose to get hit by the bicycle every day of the week.
