For me, being a car commuter can only ever be an intermediate solution. I do not want that lifestyle. I feel better if I cycle daily. I even like winter cycling, to a degree. We get ice and snow in wintertime, but studded tyres help a lot. I could well imagine adding electric assist to the winter bike, to make it faster and more comfortable. Sometimes it is just annoying. ;) It depends on the mood.
"Encouraging" people to cycle? Well it is a personal choice... but road design plays a role. I've recently spent a long cycle holiday in Sweden, and the roads mostly had shoulder lanes (rather like American highways) and I could cycle from town to town quite relaxed and with no stress between me and the lorry drivers. I liked that. Inside towns and villages I mostly prefer not to have cycle paths, but "behave like a car". It's easier this way if you have to take many turns etc., and can even be safer according to a lot of studies. Cycle parking is another issue. A proper bicycle rack will accept very different cycles and allow you to lock the frame to it. I found that to be well-solved in many Swedish cities.
Is that the tendency in Vietnam? In Germany it is opposite, and I think it's similar in many Western countries. The bicycle is being rediscovered as a practical vehicle rather than a spare time toy. So people's bicycles are growing (as it were) luggage carriers, mudguards and proper lighting systems. :)
