Vietnam is amazing. Minimal gridlock and high mobility, due to lower requirements for purchase, hire, cost, licences. Safety is an issue, deaths are statistically high. But you know, with greater freedom comes greater responsibility.

As far as electric vehicles go, it has its own issues, and can empathize with parking being problematic to pedestrians but I think that's an area that would be easier to police. Over-policing restricts freedom.

I suppose, ideally, you want to encourage all forms of transport. As a pedestrian, I don't feel safe crossing multi-lane roads with any powered-vehicle! I get your point but we need vehicles. Affordable and reliable. I used Grab motorbikes to pick me up from airports. Never had a single problem.

In other countries, taxis used to be okay (as public companies) now it's just a hassle to hail one and not competitively priced.
