VN is very diverse in everything (weather, nature, culture, tradition, lifestyle etc). Each province is like a totally different country. If you like nature and remote places you can visit the north half of VN. HCM city and Vung Tau are developed cities, the life there is better than other parts of VN. Girls there are also cooler and more sexy too. In less developed parts, the life is still fine but it's really difficult and inaccessible for disabled people.
VN is generally more 'free' than the rest of the world. I mean less laws, less rules. Or laws/rules exist but people do not care. You can fly drone almost everywhere expect sensitive places like military zones and government, council buildings, air ports etc. In the past, some foreign youtubers and some bullshit 'human rights' organizations came to VN, took videos then edited, falsified the content and announced untruth things about freedom, religion in VN. Therefore police gets more careful when seeing a foreigner taking video. But I see many foreigners keep flying drone without problem. You might have been a bit unlucky to meet those annoying polices that day.
I know in the west, the privacy is the most important thing. Nobody can violate the other's privacy. But in VN, people usually do not care about privacy of others or themself (me too). Many foreigners are very surprised of this 'culture' the first time they come to VN. Some like it, some don't. You seem an open-mined guy and suiting the lifestyle in VN
Powerchairs are extremely rare in VN. Your monster powerchair is even more strange to everyone. I bet they did not know you were a disabled person. They thought you were an engineer who were experimenting a special vehicle

When I go outside, especially in villages, locals sometimes stop me too. They want to watch my powerchair and see how it drives. Nobody wants to touch my hair or take picture with me. Maybe that's because I am not any special to them
