Seattle has the insanity of having obligatory bicycle helmet laws. No city has ever had a successful bike-sharing scheme with laws saying you need to wear a helmet. No city with that law has ever had any amount of cycling either. Medellin has plenty of hills and cycling, London has plenty of rain and cycling. Rain and hills won't kill you, unlike the pollution from cars
