Vitalik Buterin: @ChrisLundkvist 切换汽油车-> 电动汽车解决了污染问题，但对拥堵没有任何作用。 切换汽车 -> 任何类型的自行车/踏板车都可以解决拥堵问题。 我认为电动自行车更实用，因为普通自行车有点不够方便（例如，很难上坡）

原推：@ChrisLundkvist Switching gas car -> electric car solves pollution, but does nothing for congestion.

Switching car -> any type of bike/scooter solves congestion.

I think ebikes are more practical because regular bikes are just a little bit not convenient enough (eg. very hard to go up slopes)
