Data over traffic accident and injuries should define which transportation is more unsafe, especially since most traffic laws exist in order to prevent accidents. To my knowledge, speed and braking distance is the biggest factor for accident rates and injuries. The average bike speed in a flat city was last time I checked around 12km/h (7mph), which has a very short braking distance. Unsurprising the accident rate of bike hitting pedestrians is extremely rare for a flat city, where the top listed accident rate for bikers here in Sweden is 1) person falling off the bike with no other person involved, 2) car hitting bike in a crossing where the car is running a speed usually above the speed limit. A typical car driving at 50km/h (30mph) has a reaction distance of 21m, braking distance of 14m and total stopping distance of 35m. This is why efforts to reduce high accident rates for crossing involving cars is done by reducing the speed through speed bumps, cameras that publicly display the speed, and additional traffic lights. In the cases where those efforts are not enough there is usually talk about separating the traffic since the lowest speed limit is 30km/h and that still produce a risky braking distance for highly trafficked crossings.
