Earlier quoted context omitted.
Even electric bikes are not the solution, at least not in many parts of the world. What happens when it rains / snows? I don't know what the solution is though, maybe small electric cars, self driven, as part of public transportation service?
I regularly ride my "normal" bicycle (including 2 little kids in a trailer) in the rain in Berlin (where it rains for 167 days per year on average, which is ~45% of the year). You just need the appropriate clothes & gear.
Well, neighbouring country in which it rained on 199 days on average in the past 20 years or so, but since it doesn't rain all 24hrs of those days, a more interesting figure would be that it apparently only rains about 10% of the time here. Meaning about 90% of the whole time there is no rain.
